Concerned about pregnancy - messed up Pill schedule

Hi all, so I recently spent 5 weeks in the States, which meant my combined Pill schedule was a bit all over the place as there was a 6-hour time difference between my usual time of taking the pill and the new time zone (typically I take the Pill at 9am GMT). After the initial few days I switched to the new time zone and began taking my pill at the same time of day as I would in the UK (so 9am American time); I had my scheduled bleed on my first weekend there, and resumed taking the pill on the scheduled first day of the new pack.

I came back to the UK last week and tried to get back on schedule with taking it at the usual UK time. In all the time I was away I never missed a pill and the maximum time difference would have been between 6-8 hours, which occurred during the first few days I was there and adjusting to the time difference. During all that time my boyfriend & I continued to have sex, and he did ejaculate inside me a few times. I am due a bleed this weekend (typically arrives on a Friday evening) but so far nothing. I know I am probably panicking for no reason and that the changes have just caused the bleed to shift around a little timewise, but I guess I am just looking for some reassurance!

Thank you.

Have you done a pregnancy test? If not it maybe worth trying one if you period hasn't arrived by Monday.


Hi there

By what you are describing it sounds like you did not miss any even with the time difference. A pill has been missed when it is more than 24 hours since the time you should have taken it. If you have missed one pill, anywhere in the pack you should take the last pill you missed now even if it means taking two pills in one day then continue taking the rest of the pack as usual ( no additional contraception needed) and then take your 7-day break as normal. If you want to be reassured a pregnancy test will be accurate 3 weeks after the last sex.

I hope this helps

Best wishes

It might be an idea to set an alarm on your phone for UK to avoid confusion, I know a few of my friends who have done that and said it helped. x
