Thank you all for your suggestion I will speak with my doctor
Try taking Vitex Chasteberry to regulate your cycles and invest in the Maybe Mom ovulation microscope to know when you ovulate.and Good luck:)
Eat healthy and exercise. Take pre natal vitamins. I will also suggest to go straight to a fertility specialist. They are more attentive than obgyn. Will give you a thorough checkup.
My husband and I are ttc also. We've been trying for a year. I am 25 as well. I had the exact problem you have. I just got diagnosed with pcos. I'm not saying you have it but it would hurt to talk to your obgyn.
You may not be ovulating if you are missing periods. I would use the ovulation predictor kit and see if you ever get the two blue lines. If you never get two blue lines then I would speak to the dr about going on clomid or something that can maybe induce ovulation. Best wishes!
Sounds like your body is going through a lot, I was like that a couple of yrs back before TTC
Try to do exercise or yoga to promote happy ovaries and menstrual cycle - keep the faith and apparently the doc told me I'm still young too so there's lots of hope
