hiya i have a question concerning my pregnancy . I am currently 25 weeks and 4 days pregnant . My last period was on the 7 of october or what im thinkin was my period. I had unprotected sex 2 days before my period and afterwards i took the morning after pill . My period came on time on the 7th but it last two days . Very heavy at first and then lightened off there was a flow not just when i wiped . two weeks after my period i had unprotected sex again on the 22nd of october . My doctor when from my lmp on the 7th october and said that i was 16 weeks along . I had m y first ultrasound on the 27th of january and i was told that my dates were correct and that infact baby was measuring 16 weeks . so i was 14 weeks from conception . I had my second ultrasound on the 9th march i would have been 22 weeks and i was told that baby was growing well . I booked in for a a private gender scan and 3d scan when i was 24 weeks . i was told that baby was measuring 24 weeks plus 2 days and she said everything seemed ontrack . my question is is can i safetly say that my baby was conceived from the 22 of october intercourse ? and not from before my lmp when i took the MAP. I read about implantation bleeding aswell but since my baby is measuring on track and that my estimated conception date would be around the 22 of october do i need to worry
