I and my boyfriend had unprotected sex on 23rd sep and i took an ipill on 25th sep. Again we had unprotected sex on 26th sep and due to fear ,i took an ipill again on 27th sep. However,both the times he didnt ejaculated inside but maybe it went? And again we had unprotected sex today but under 24 hours of the second ipill i took a night before. He released outside my vagina but i'm not sure of the precum or anything. I usually get my periods 5 -6 days prior to my date and my date is 2nd october and i still have not got my periods yet.Will it cause any problem to my body or any chances of pregnancy? Please help
