I'm a 16 (almost 17) year old girl who's had my periods since I was 11. I've kept track of them and for the past 4 years they've been routinely regular with one exception where it was a month late.
I finished my last period 10 days ago (it went for 4-5 days) and I noticed blood on my pants. I've bled through my underwear into my pants and this has never happened to me before. I've never spotted (but this seems heavier than spotting, I am wearing a pad now) and I have also been having abdominal pains, really bad fatigue and nausea and been heaving into the toilet (with nothing coming up).
As this has never happened before I'm slightly freaked out. Does anyone know what could be causing this? Should I contact my gp?
* I do have a symptom based diagnosis of Endometriosis from a gynacologist but never had a laparoscopy to confirm.
