AJS012 • #1👶💗 #2 👶💗 #3 on the way

We havent gotten pregnant yet...(its only been 4 months) so I started getting ovulation tests and testing. I havent gotten a positive test yet... granted I haven accidentally missed days, gone on vacation. Etc... my periods have always been normal 5 days every month never missed a month. what else should I be trying to track to figure it out? I'm very worried... I know I shouldn't be but I cant help it. Please help.
