To increase my chance of ttc is it really possible to get pregnant on a period like what is the percentage. I have really regular cycles 20 to 25 day's & i have noticed that i ov on or around cd10 my actual period last from 3 to 7 day's & last cycle only 20day's & i had stong positive opk cd 5 & peak opk cd6. I wasn't sure if it was a true positive though. But now I'm wondering if the reason I'm not getting pregnant is cos i ov very early in my cycle. Obviously I'd babydance while on my period but cos never done period sex I'm freaking out about the mess. & I'm also wondering if cos possibly ov like really early many while still having a period that this is why i don't notice any ewcm.

Sorry for any typo errors

I know i should of stopped opk cd5 cos peak but when never ovulate that early i was really shocked & still bleed light cos was towards end of my period that stopped cd6
