Im In the midst of an fet and taking prometrium vaginally 3 times a day. When i put it in this morning i noticed a tiny hard bump (size of a grain of rice)almost like a ridge at The side of the opening of my cervix. I had a hysteroscopy a couple months ago and a transvaginal ultrasound last week and no one mentioned seeing anything. Ive had 3 previous vaginal deliveries and it almost feels like a bit of scar tissue…..
