HI there, please can I get an opinion, I've just came of the YAZ pill 3 months now which I was taking for about 8 months, and period was on time for 2 months since of the pill, this is the 3rd month and I'm 3 days late. I did a test this morning but its negative and my breasts are sore for 1 week now, I have a little discharge this week n some cramps. In the past I was irregular but a doctor helped me balance before going on the pill... what could it be?
