TTC for over a year 💔

Why is it so difficult to get pregnant 🥺 I have a daughter who just turned 4. My boyfriend (not her biological father) has been in my daughter’s life since she was 2. You wouldn’t be able to tell he isn’t her real dad. He has no children. We’ve been trying since I came off the Nuva ring in July of 2018. In the past I’ve gotten pregnant without even trying and now it just seems like it’s never gonna happen. We’ve tried fertility supplements for him, I track my ovulation, and we’ve tried using fertility lube like pre-seed. No luck yet. Don’t wanna take the route of seeing a fertility specialist because I know that stuff costs money. We both have insurance but still. I’m 3 days into my period and I’m just so emotional ☹️☹️☹️
