Most time I climax or have an orgasm with my husband my vagina pulsates. It is like a contracting motion. Now that I am pregnant I am scared this may harm the baby. I am 7 weeks. I am going to contact my doctor but I wanted to know if anyone else has experienced this or know what complications could arise?  I would love to have sex with my husband as we are both very horny with all this hormones going on!
