I hope that someone can help me I am 21 weeks pregnant and I have the stangest feeling. At my pelvic area it is painfull and it feels like there is (hope it come's out right) "bubbles and at times it feels like it pops" in my stomach. I just want to know if it is normal, I don't have any blood spots or any coloured spotting. Hope that someone can help it is my first baby but had a miscarraige before at 3 months. My feet are also starting to swell and I don't know if it might be too early for that.
