My husband and i are TTC for a second baby and I am 2 days past ovulation and we did the deed day of ovulation. I have been gluten free for coeliac disease the past 2 months I have been feeling better in myself no upset stomach in the mornings. However this morning I had very bad period like cramps felt sick and had severe diarrhea and I should mention I never had diarrhea this bad while I was undiagnosed coeliac disease. Then I had lower back pain afterwards is it very likely I am having symptoms of implantation? Could I already be showing signs of early pregnancy?
