Maybe this is HARDER than I thought it would be

I got off bc last March. We wanna try for a kid. I’ve read from multiple sources most women get pregnant within the first year they are off bc. So I got excited. But that hasn’t been the case. My cycles are VERY irregular. I haven’t had a period since November. They are always months apart. I’ll get the feeling I’m on my period but no blood, nothing. I don’t know if I even ovulate. I feel nothing. Im getting sad, I feel like well maybe my body just isn’t made to get pregnant. I don’t know what to do.
