62 days

My cycle has lasted 62 days!! Idk what to do anymore. I called my family doctor to see if they would check my thyroid again (I have Hashimotos and it's put my cycle off before) and they said they have to wait 10 weeks before changing a dose so I need to wait 6 more weeks to see if that's a problem. Should I call my OB/GYN and see what she thinks since it's her area of expertise? Whenever my cycles last this long it makes my periods excruciatingly painful so I'm really nervous. PLUS it's screwing up TTC. What would you do ladies?
