Hi, i am going to try to make this as simple as i can (seeing as its not). I have been on YAZ for three months now after being switched from Orthotrycyclin (abnormal bleeding). The first month of YAZ, i again had abnormal bleeding for 6 days (heavier than a period) about a week and half after my period. I figured it was hormonal changes. I was told to double up on my pill for 5 days and see if it would stop. sure enough it did. i went on vacation and immediately started bleeding again. 5 days of "abnormal" 3 of what was supposed to be my period. <<my cycle was messed up because of doubling the pills i am guessing. i was supposed to start my new pack on a sunday (and it was only tuesday) so i waited the week out (no protection). I was then put on an antibiotic (which i read that it completely cancled my pill) the week i started taking my pill again. so technically i have been unprotected for two weeks. i have had unprotected sex a lot. i am now a week and a half away from my period's due date. i have been experiencing a lot of abdominal cramping for almost two weeks now, and my boobs are very sensitive. almost too sensitive to take a shower (they have calmed down a little though). i was wondering what are the chances that this sounds anything like a pregnancy?? or is it just the pill/period?? < sorta hoping it is a pregnancy!! anything will be appreciated:)
