Mine feel like a tightening of my uterus - to the point where it feels much harder to the touch than normal. Sometimes they are just at the bottom, but other times they creep up all the way. Mine typically don't hurt and aren't really uncomfortable; it just feels like a muscle tightening spontaneously. I did have a little pain with my ligaments (in the front) once or twice, but normally it's just a weird feeling.
FTM often don't feel them or if they do feel them they are light - more of a tightening feeling in the abdomine and sometimes an achy feeling in your lower back/hips.
StM+ often feel them earlier and they are often a little more noticable. Same tightening in the abdomine but it's paired with a lot of back tightening and achy lower back/hips. When you touch your stomach you'll notice it'll feel hard(although I'll have tightening without the hard feeling stomach)
With DS i knew I was contracting but I didn't feel it all, this LO i started having them pretty early and as time has gone on they've gotten more intense. I feel them more in my pelvic area and lower back. Overall just tightening. You may also notice your LO will go pretty low or push down pretty low.
I just started noticing mine at 34w and if my doctor hadn't noticed it happening (she was feeling my belly at a regular check up) I probably wouldn't have been tuned in to them. To me they feel as PPs have said - a tightening and a light menstrual cramp. They've been happening when I lie down or get up mostly.
