Hi, I started taking microgynon to see if it cleared my skin up. We usually use condoms but didn't use one on day 4 of me starting the pill. I started on last(5th) day of my period when I just had spotting. My period is regular around 25/26 days, I think. I took the pills properly at same time everyday. I wasn't on any birth control before for 2 years just condoms. I'm in a happy stable relationship of 5 years so wouldn't be a bad thing but could I get pregnant? We also had sex yesterday without a condom which is day 11 and took pill 10am everyday without fail. I have been showing symptoms like sore breasts, nausea, headaches, tiredness, light sharp niggling pain in my left side low down, backache etc. Could this just be effects of pill?
