Giving up

I have been trying to get pregnant for over 3 years now with no luck! That’s not my biggest issue with giving up! I have always ALWAYS had regular periods! I have never been late for more than a day. In the last 8 months I’ve been late by a week or 2 and was sure this is it only to get it the day after I take a test! Like I feel like it’s the universe playing a mean joke on me. I’ve decided I’m not trying anymore and I can’t afford to go through fertility clinics and stuff.
