After I found out I was pregnant, I had sexual intercourse. Any time I masturbated I use to get slight cramps after. Went in for a 16 weeks check up and my cervix was damaged and a cerclage had to be placed. It had been 14 days since the cerclage was placed and my hormones got the best of me and I masturbated and there were no cramps. Reading up on it after the fact I realized this was a bad idea and it won t be done again. But should I go the the ER as I m really scared after reading?
