I'm a first time mommy and am close to 38 weeks right now. I feel as though I may be having contractions that are pretty consistent, but then again I don't even know if they ARE contractions! Anytime I ask someone what I should be looking/feeling for I get the annoying, generic answer- "Oh you'll know!" Could someone PLEASE give me a hint as to what I should or should not be feeling when I'm "contracting"? Right now I'm feeling pressure/tightening in my lower pelvic region, but a lot of times I have a lot of lower back pain. Help please!
