My Lmp was on Feb5. I had protected sex with my ex the day my period went off. The next week I had sex with my boyfriend unprotected. Ive been having sex with him unprotected for almost two years now this. Im confused who might be the father because my boy friend had testicular torsion

If you are confused have a paternity test done..

If your LMP was February 5, you most likely conceived on or right around February 19.

This is only a guess and in no way will subtitute for a DNA test. You will have to have a DNA test done to establish paternity.

Yes, the dates of sexual activity is far too close to know till after the child is born and a DNA test is done
