Fertility

For my fellow girlies....is it normal to have sex around ovulation and not get pregnant at all...say like two cycles.Si eti I'm wanting to have kids at the moment but Sasa I find it strange how I'm not pregnant 😅.Is it a fertility issue coz lately I've been spotting around ovulation too.Like I can literally tell you the exact time I am ovulating ju I cramp for a few minutes and then I spot and then it's gone.Its kinda stressing me out but again gives me confidence to have raw $ex ju nimejiconvince I'm probably infertile! Any doctors with any insights??!😅
