Vaginal pains

Abbey • I'm 22 years old, married, one angel baby, one earthly baby, and one baby on the way.
So I'm 16 and a half weeks, and today I had a major belly growth spurt, and I've been having stretching pains, but now my vagina hurts like super bad, it's like an aching pain. Is this normal? Has anyone else had this happen? I'm only really concerned cause last time I had vaginal pain like this I ended up miscarrying at 5 wks.
