Hi I am 30 and I started taking the pill 8 weeks ago, took it for two weeks and during the third week of taking it had unprotected sex for a week, then had to take antibiotics at the start of the fourth week, took all the pills as normal during this period, I missed a pill Tuesday 3 weeks ago, so during the fifth week of the pill, started light bleeding on the Thursday with some constant cramps and have been bleeding since, going for nearly 3 weeks now, it doesn't look like spotting, is this break through bleeding or could I be pregnant?
