I am 36 and had been taking Yaz, I was 3/4 through my 4th month when I stopped taking them because all the negative info I have been seeing on it. I have never taken BC pills before, but started taking them to regulate my period, minimize cramping and large blood loss. I had a few episodes of break through bleeding, once for a whole week on the 3rd week of my 3rd month of Yaz. At the end of that week of bleeding I had sex and used no other form of BC. It has also occured to me that earlier in the month I missed one pill but made up for it later, taking 2. I always took my pills within the same 2 hours at night. Sorry for the long exlaination ... I guess my question is, the fact that my breasts are sore now and not during the months I actually took Yaz, could I be pregnant? I have not gotten any sort of bleeding at all since stopping Yaz 2 weeks ago. I have also taken 3 pregnancy tests in the last week because I just wansn't feeling 100% right but they all came out negative. Is it possible to get 3 negatives and still be pregnant? The pregnancy would be a result of the sex I had over a month ago ... so can I assume the test would have come up positive if it had happened then? I know Yaz and any BC pill can screw up your hormones but I never has sore breasts while on Yaz ... why now suddenly 2 weeks off?
