I am like you and don't know whether it is normal not to ovulate seeing as before my miscarriage I ovulated every month.
Even with a " textbook " 28-day cycle, it is not necessarily the case that a woman ovulated on day 14.
Some clinics seem to prescribe C for 3 months, then if you hav n't ovulated, move you on to another treatment.
If the woman has recently ovulated, the sperm may connect with an egg.
Unless you know the exact day you ovulated and there was at least a week in between having sex with the two guys, we don't know.
