Just let ur dr check it out...but from what I heard - the Babies are quite strong and well protected!! Goodluck!!
I hope that's all out is because my son Saturday night kicked me in the stomach and ever sense than I have been having horrible pains.
I am also 22weeks, and were experiencing pains especially on my left side... I called my GP and explained, she said its just a muscle.. The pains are gone now, and Baba is active.. Hopefully its just a muscle pain that u experiencing, but u should rather consult - rather safe than sorry!! Good luck!!
