My husband and I have been TTC for fourteen months. I am a example that it can happen at 38 years, endometriosis, left ovary severely scarred, a total of four surgeries to remove huge cyst on left ovary each time.The last surgery was October 2018 and before that each year going back four years and one round of clomid in February. I honestly was starting to feel hopeless. I thanked God like always for my son who will be 19 years old in July and told myself to be happy I was blessed with him.So to get pregnant after all this it is truly amazing and nothing but God.This app was also very helpful and accurate for the most part. Ladies don't ever get up.
