I have been on the pill for 12 years, however last month I had very bad d&v and ended up having a withdrawl bleed, mid-pill. I had sex with my husband on lots of occasions, last time 23 August. When my break period came after 21 days, no withdrawl was had I took my pill again after the 7 days though. For the past 2 weeks I have experienced swollen breasts (gone up at least 1 cup size), change in nipple shape and nausea but no vomiting, the nausea starts like clockwork at 11:45am (ish). I have done 5 tests over 2 weeks all showing negative. I don't want to bother a GP with some crazy I think I'm pregnant rant as I don't really think I am, as symptoms are not 100% consistent with but I cannot imagine what else can be causing the nausea (could it be the stress I think I could be)?
