34 and worried

My bf and i had sex last april16 i thought i'll get pregnant since based on the app it's the start of my fertile window.i took a pt test 14days after our intercourse and 1day before my period.it came out negative (sighs) i really wanna have a baby soon i'm afraid i don't have the capacity to bear children. My period is due tom so if it's not delayed we'll just have to try again,problem is he's deployed already. 😢😢😢
