I've been on the pill for the last 7months. but lately I've been taking antiobioixic and havn't been following the 7day rule. for the last 3mnts I have been getting REALLY BAD camps in my stomach when it got real real bad I nearly passed out and got sick and had to go to the doctor's. they have done an ultersound and found nothing and are sending me for more tests. and now the other day when i was having intercourse with my partner i started to bleed this isnt the 1st time this has happened!!.. i have put on a bit of a bump but i'm changed my diet. I am having my period's sort of regular but they have started coming four days after i have stopped taking my pill. they use to come on the night of the 1st day or morning of the 2nd!.. Please help it's driving me crasy and making me have way more mood swings!!...
