Hi im 26 year old female. 125 pounds 5 6, 11 weeks pregnant. Have SVT and tremors. I have this twitching right under the left side of my eib cage and a tad bit below it. It was twitching very little for a couple days and for the past three it has been non stop. Idk if the pregnancy plays part in it. But there is no pain while its t Witching but pain very rare when i stand up or walk. Doesnt feel like a muscle pulled and this is my 4th pregnancy. Only one live child. Pregnancy has gone great so far. So i dont think it has to do with that either. Got any ideas? Oh and i have been really constipated and have been eating fiber inriched food to help with that.
