Not able to conceive...(?)

My significant other and I have, for about 3 months straight had unprotected sex and have not been worrying about where he ejaculates. 90% of the time is in me. We have not had any luck getting pregnant or having a pregnancy scare. I'm really starting to think we are not able to conceive. This would kill me. My period is in six days, during my ovulation week, we made sure to have sex every day. Anyone have any advice/thoughts? 😖 I feel like I need to give up!
