How long does it take for the uterine lining to thicken after weaning?

Hi doctor,

I exclusively breastfed for 17 months, while trying to conceive a handful of times. I believe that I conceived, but implantation failed. My gynecologist suggested to wean and then try, and maybe my uterine lining needed to be thickened. I weaned two months ago, and so far both cycles have ended with a period, which was normal 26 to 28 days cycle. I believe, after the 14 days luteal phase, I have conceived because after every time we try, I get nausea along with pregnancy discharge and other pregnancy symptoms. But, then implantation does not sustain and my period comes. I am wondering if you think this is an implantation issue due to the thin uterine lining, is from breastfeeding or something else? And if yes, how long does it take for your lining to thicken? I do not want to keep putting myself through this again and again.

Hi doctor,

Thank you much for your reply.

Do you want me to get a scan done around ovulation to see if I am ovulating, or to check for something else like a fibroid? Because it was mentioned four years ago, that I had one fibroid, but the gynecologist at the time was not concerned. I did have a 21-day test, and it came back 5.2. So, I believe I am ovulating. I am also on prenatal medicine, 1 mg of Folic acid. Do you know how long it takes for the lining to rethicken after weaning?

Hi doctor,

Thank you for the detailed information on having a scan, that really helps. Is 1 mg Folic acid not enough? I have attached a picture of all the medicines that I am taking.
