I wonder

I never took birth control at all only used condoms so I'm curious to see since i never had hormones from birth control if that some how will help me get pregnant quicker cause my body doesn't have to go back to having a regular period I really hope this is our month!! My fertile window is 12-18 so instead of everyday like last month were going to try 12,14,16,18,20 just to be save not trying to think anything of it but just have sex on the days I know I should then just let it be not test not lookup. Symptoms just have sex on the days I need to and then just continue on and hope I get my BFP 😬
