Concerned and Sad. Advice or info, please? 🙁

My period is 68 days late and I’m on cycle day 103?! I’ve been trying for a little one and no luck. Negative tests too. Before on my period i didn’t have any luck either but I’m starting to think my missing period is playing a part in my fertility now. The doctor has only told me to take bc to normalize it. I don’t know what to do.. please help.
