I have terrible pain where my thighs connect to myb pelvis
I'm 21w and I also get sharp pains when I turn over sometimes or if I get up too fast But my dr said that its normal. So I wouldn't worry :)
I had severe pains in lower abdomen during my 18th and 19th week, doc checked and said everything is fine and i had painkillers. Now ai am 20 weeks and I am fine. Still it becomes difficult to move and sleep switching sides. Unless there is any bleeding or something, no need to worry.
