Hi hun

IMO yes you can conceive with when you DTD and what the OPK readings are. Remember sperm can live for up to 5 days more or less if given the right environment.

Good luck!

PS Don't know if fertility is hereditary but I do know that my sister and I (only have one) have conceived within 1 - 3 cycles of *trying*. My DH comes from family of 5 and his father a family of 13 also ....
