This is my second pregnancy, so I'd like to think I would know better. However I never had this feeling towards the end with him, labor was a totally different experience. I've been having strong menstral like cramps all day. They range from mild to painful. They aren't regular to the point I can say I have so many spells per hour, but they are pretty frequent. It's lower abdomen, pelvic and upper thighs that are feeling the most of it as well as some lower back pain. Baby seems to be slightly more active through the day than he normally is. I've been extremely queasy all day, but no vomiting. Just getting waves of nausea if I move around too much. It's hard to get off the couch today, but I've tried and it doesn't help to ease anything. I've also been drinking water.
