Ever since I can remember my cervical mucus has been pretty thin and I was VERY filertil. After I had my son which he is almost 5 now I was on birth control and I notice since I have been off of bc my cervical mucus isn't noticeable at all and I can't get pregnant. My husband and I have been trying to get pregnant for 7 months now and I did get pregnant once but unfortunately I lost the baby at 6-7 week's. Can this be caused by the birth control that I was on for so long and can this be reversed? I'm stressed out and very sad that getting pregnant is becoming to be impossible.
