Bless you, your post sounds just the same as I felt a few weeks ago.
My diagnostic lap was on Monday 1st May last week...I really hope I can help you feel a little better...
With regards to the not eating on the day, I was feeling too nervous to really want much to eat, and I'm usually a "breakfast as soon as I wake up" kind of girl!! It's really important however to make sure you don't eat after the time they give you, so definitely listen to the guidelines. It can be a little uncomfortable as you may begin to feel hungry, however lots of magazines or whatever you like to read or do will help to distract you. I would really recommend that you take a couple of bottles of water in your bag, as it's likely that your mouth will be really dry afterwards. They will obviously give you water but I found I needed more!
My period was also due the day after my op...and came bang on. I've been having quite heavy periods (one of my symptoms) and this one has been no lighter to be honest. I did find the pains slightly less, however I was taking more pain killers than normal so it could've been due to that. I took paracetamol and ibuprofen for the first 4 days every 4 hours during the day. It's such a personal journey, however I found that taking them regularly rather than waiting for the pain to get bad, then taking them, was definitely better. Make sure you've got a good stash of paracetamol and ibuprofen at home. The hospital may give you some, but I'd stock up just in case. They also gave me 30mg codeine which really made me quite drowsy so I just stuck with the paracetamol and ibuprofen. You said you've been taking some codeine for the pain already though, so I'm sure you'll be ok.
It's a week tomorrow since my lap, and I know I keep saying we're all different, however I just couldn't go back to work yet. My job is mainly office based with a fair amount of walking around here and there, so not the most physical, however it's my low energy levels at the moment that are stopping me. Today has been the first day I've not felt distant, so I did more than I've done so far this week and have felt completely shattered this evening. Honestly, don't push yourself, it really is a little at a time...I've been wearing my PJs every day until today. I read online somewhere that surgery is an event and recovery is a process, and it's so so true. Your future self will thank you for giving yourself the extra time that you need now. My consultant signed me off for 2 weeks without even asking me, so I'm sure that must be standard. The form for work was left with the nurse to give to me. Your body is forever but it's likely that your job isn't. I really want to say please please please take the time off that you feel you need. Listen to your body and do what you feel is right for you...NO ONE should tell you when you're ready to go back.
In terms of your family and friends...there is little bit of literature online that you can give them to read. I need to wait for my follow up appointment (6 weeks post op) to find out the next steps. I was due to have a hysteroscopy as well, however the surgeon couldn't access my uterus through my cervix! I didn't see the surgeon who did my op after the procedure, however he did come to have a quick chat to me beforehand, so fingers crossed they will come and meet you too and you'll be able to ask any questions you have. I wrote my questions down beforehand and I was so glad I did. An empty tummy also empties your memory
I would also say the same as the girls here...an oversized nightie was my saviour, especially at night time. I had 2 incisions, 1 just below my belly button and 1 over to the left. I went to primark and brought some comfy lounge pants for £5 and I wore these home from the hospital with a baggy t-shirt and my slippers. I'd suggest getting lounge pants or leggings a size larger than you would normally. Your tummy may be a little bloated from the gas afterwards and also you can pull the waistband up a little higher. If you get shoulder pain from the carbon dioxide they use, the best thing I can suggest is to gently move around if you can. Moving definitely helps to disperse the gas. I drank peppermint tea too and I think this helped with the bloating slightly. And a hot water bottle is also good.
And rally as much help both emotionally and physically from friends and family. Even if it's just a message once a day to say they're thinking of you, it helped me so much. People usually want to help but just don't know how to, so to be honest, I think they're grateful if you let them know what you need.
This may sound a little silly however I wish I'd built up a little upper body strength. I found sitting up in bed for the first 48 hours a little tricky on my own and some slightly stronger arms would've come in handy, so I'd suggest doing a little upper body strength work, unless you're pretty fit already And, stay as healthy as you can over the next 10 days...good food, fresh air and plenty of sleep.
Also, it might be worth stocking up on some night time sanitary towels, just in case your flow is a little heavier.
We've got some lovely weather at the moment too, so really make the most of sitting out in the fresh air when you feel up to it. Also I've joined Netflix and got a free month...and definitely got my money's worth already
I wish I could tell myself this time last week that it's not going to be as bad as I thought it was. The medical staff are all understanding and kind. They will look after you! You will be safe and they are experts in making sure the best is done for you. I know it's easier said than done, however I promise you, the more relaxed and positive you can be, the better. I don't know if you're into breathing techniques or meditation, however I found listening to some pre surgery meditations on YouTube really helpful.
I'm quite new to this forum and I've not posted here before, however when I read your post I really felt I wanted to reply. Take lots of care of yourself, and take the time you need and deserve.
With lots of love xxxxx
