Hate this feeling 😥

I'm so confused and lost. I never had this in my life and I don't know what to think or do. I tried for almost a year with my daughter. Now my daughter is almost 4 and we are trying for another. It's been six months since I have been off BC. I missed my second period completely and since then my periods have been so weird. I'll spot for like 6 days and maybe be heavy for one or 2. My cycles are like 6 weeks long. Now month six I'm 11 days late on my period and no discharge at all. And have taken numerous tests and they are all negative. I'm worried I'm not even ovulating at all. Basically since I've been off BC my periods are not right. I've had blood tests to check my hormones and they came back fine apparently. Now the next couple months my husband is going to be gone training (army). I'm debating on going back to my doctor and simply asking what the hell is wrong with me? When I tried with my daughter my periods were never like this. I've heard people say they had to be put back on BC to regulate them and all kinds of horrors. My biggest fear is not ovulating because then what? Ugh sorry rant over, I just don't know what to do.Â
