Husband can't make up his mind

My husband and I have been married for 2 years and together for 5. We have always talked about having kids pretty much from the time we started dating. I have wanted to have a child for as long as I can remember. I have PCOS and have never had a cycle monthly without birth control pills until the last 5 months. They still aren't exact but between 28-30ish days apart. With actually having a normal cycle it has seemed important to me to start really really trying as in tracking when I would ovulate, checking cm and cervical position, etc. It has done nothing but lead to fights it seems. One day he is on board and wants a baby as much as I do. Then one night I tell him I think I'm ovulating and he's too tired for sex and the next flat out says he doesn't think a baby is a good idea right now. He has valid reasons (wanting to be more financially stable and I'm starting school in a few weeks) but at this point I feel like it's one big mind f*ck. I don't even feel comfortable discussing my want to try for a baby anymore and try to convince myself I don't but every month when my period is due I still find myself trying to spot pregnancy symptoms I may be having and obsessing over the glow app. I don't want to have a baby if he doesn't right now but I'm tired of feeling like its totally his decision. And it kills me feeling like if I was normal and could conceive naturally (we've had unprotected sex almost our entire relationship with no pregnancy) we would have already had a baby. Am I being unfair or just too sensitive? Does anyone else have this issue with their SO? HELP! Sorry this is so long!
