I had my periods on 5th September and had sex on 14th September using protection,but when he was pulling out the condom got stuck but he had pulled out, though he was pretty sure that nothing had happened,we decided to pop in an I pill in case something goes wrong.. 4 days after taking the pill I started to bleed like I was in my period but without any cramps for 3-4 days,was it an early period or withdrawal bleeding? I haven't got my October period...am I pregnant or is the pill messing up with my cycle? I have started to receive very mild cramps since 2 days now,no other signs like back pain,nausea or anything.. do I need to worry?
