What’s wrong

Vanessa • TTC for my rainbow 🌈 #clomid TTC past a year now

So I haven’t had a period since March 22 and I’m not preggo I had that confirmed via blood work, I just wanna know if anyone else experienced this what could it mean? I’m TTC and it’s very difficult especially because I don’t know what tests to demand all I’ve heard is the possibility of being infertile.... if anyone has a similar expirience but has some medication or diagnosis I would appreciate it
