hi, I'm on the cileste pill, i've been on it for about 5 months now, the first month i had sex 2 days before my first withdrawal bleeding am abit worried because i varied taking the pill at about half an hour here and there, he also wore a condomn, I've had 5 withdrawal bleedings since then, what are my chances of being pregnant?? i have 2 kids already but never saw bleeding during pregnancy
