Severe right abdominal pain

Marika • Momma bear to two little Cubs
Hello everyone,
This is my first post. I found out I was pregnant about three weeks ago from a hpt and then went in for a blood draw and I was definitely pregnant. I have a history of ectopic pregnancy and then was pregnant and had an ovarian torsion and two huge ovarian cysts and endometriosis everywhere. I was rushed into surgery they said once they removed my cysts the ovary untwisted itself so I still have both ovaries. Well to try and make his somewhat shorter I have one three and a half year old and his is my fourth pregnancy. I've been having some lower right side pain (I no longer have my appendix) and we have already had two ultrasounds the first was early and they barely saw anything the second was last week and they saw and heard the heartbeat and also a uterine polyp. So since then I've had little nagging pains but nothing severe. Today when I even move my pain is like stabbing. Only on my right side. I called my doctor and he wants me to go into the er but I can't go until tomorrow (I'm a military wife in DC and it's just my husband and my son and me) my husband gets off work late and asked if we can go tomorrow but I am starting to feel the pain even resting. No bleeding or spotting, just wondering if a polyp can cause this much pain and I'm over reacting or if this could be something worse. Thank you ladies for reading I really appreciate the help!
