Hi, I've just started back on the contraceptive pill, I took it on the first day of my period and the instructions say that this would protect me from pregnancy straight away. I have taken the last tablet today so will be due my withdrawal bleed in the next few days, but I am feel really sick today, and smells are making me feel worse. Its only been about 3 weeks since my period as I started the pill on the first day. I have 3 children already and this is how I felt with them although I was never actually sick. I have had lose bowl movements for a while but didn't really think of this before now. Is it possible that I could be pregnant? Feel that it would be too early to take a test.
