Kinda worried 😔🙏🏻💗👶🏻

Ok. Hubs & I just started ttc... like 4 weeks ago 😑 anyway, prior to that I had Implanon for 6 years, then took the pill for MAYBE a year... I have been off for almost 3 years..? A long time. Anyway, I recently lost over 100 lbs, wayyyyyy over exercising caused me to lose my period for almost a year. Well, I’ve been regular the past few months after forcing myself to put on about 30 lbs and cutting wayyyyyy back on running and other exercise. I’m 31. Question is, did I ruin my chance of conceiving by being on BC that long and losing my period for that long? 😔 we just started trying at the end of my last period so 4 weeks ago.. so I know I shouldn’t worry just yet, it’s just hard.
