hi guys I'm about 6 weeks pregnant and I'm very nervous because I have cramps. their not bad to the point where I drop to my knees and I'm not bleeding, however I am noticing this I'm about 5'8 132lbs my first ultrasound is the 22nd I've heard it's because I'm small and I'm stretching? ??! lmk What you think.
