Skipped period, now won't come to ttc


So I skipped my period with bc pills for maybe two years or so (with a few exceptions) but every time I got my prescription late or decided to let myself have a period, it came immediately. Now that I'm trying to conceive and get a handle on my most fertile days it has been over a month since I stopped taking the pill and... NOTHING. My doctor has not been helpful. Please. Do you have any words of wisdom? I'm so stressed and frustrated!! Thank you so much!
