Advice Please..

Kris
Anyone 17 weeks or around that point and feeling intense pressure in the lower abdomen/vagina.. feels like my baby wants to fall out of me! I recently had a infection that I don't feel was cleared up by my OB swears I don't have one (Itching.. burning.. yea no infection. . Right!!). For about a week I've had pain which I chalked up to round ligament or uterus stretching but the pressure is serious. What is this?? Thanks
