My daughter was very low in my pelvis the whole time. The Dr. at my first checkup thought I miscarried until I told him where I usually felt her move. Along with my sciatica, at the end, I had this feeling like two people were on either side of me trying to tear my pelvic bone apart like people do to a wishbone. It was horrible! That lasted for 3 weeks, and got really bad at the end. When I got to the hospital the morning I delivered I was shocked to find out they were actually contractions. Even seeing it on the little machine I was watching it and didn't really believe it, but once I got meds in my system, the pain was gone. My contractions with my son were NOTHING like that! But, it got worse at home, and I got sicker and sicker, and finally went to the hospital to make sure the baby was okay and two different people measured me about 2 hours apart. The first one-a nurse- said the dr. usually measured very generously so I might be there for a while, and they might try to induce or give me a c-section in a day or two. My daughter was born-without any of that- 6 hours later. If you think it could be labor, you really need to have a Dr. (or whoever is delivering) check you and see. My son was a textbook case and I didn't understand how anyone couldn't be sure, but with my daughter I really didn't expect to have her 8 hrs after I got to the hospital. I just thought I was sick and that it might be causing a miscarriage. It turned out I was sick for a week b/c of her. The moment I got an epidural I was perfect, and once she was out there were no problems at all.
