Help ladies! Healthy 25 year old TTC. Been off birth control for 2 years. During the first year or so I did an extreme diet and lost 40 pounds ( for a competition) . I have since gained most of it back slowly to be back to my normal healthy weight. I lost my period the last two months of the diet as I was about 10% body fat. I have had my period ever since without skipping a beat. HOWEVER over the last 6 months it has been getting longer and longer. went from my normal 25 day cycle to 27 then 29, 31,34, 38 days! I'm on CD38 right now and it's annoying as hell cause I dont know how "late I am". i recently had blood work done and everything was normal. anyone else experience this and had it go back to normal? my doctor says I do not have PCOS or any other obgyn related conditions.
