Everytime my husband and I have sex and he finishes off inside me I always have this heavy feeling in my uterus the day after. It s kind of annoying. I m not on bc and we don t use anything. We re not trying to get pregnant but we re also not avoiding it either. I ve been off my bc since last September but I also have a thyroid condition that I m medicated for. I was just wondering if this feeling is normal or if something else is going on and that s why we have conceived yet.
