Sounds to me like it was your ex that impregnated you. He doesn't need to ejaculate inside you to get you pregnant. He can get you pregnant with his pre-cum.

Have you gone for an ultra sound and a blood test? These will determine when you conceived and how far along you are.

Good luck!

Could very well be your b/f's because you had sex on the 2nd and sperm can survive days inside your uterus but it dpends how long your cycle is

Ovulation is a tricky thing.. If you don't have a regular cycle you could get pregnant during your period, right after or before your period. Check and see if your cycle is regular then check to see when you ovulate. Sperm lasts at most 72 hours tops and the duration for ovulation is approximately 5 days.

If you are pregnant and still unsure of who the father is take a dna test when the baby is born.

Hope that helped,

To me it sounds like its your bf cause 1-14 days after your last period would place you closer to the time you had sex with your bf instead of ur ex.

Good luck
