I am 17 + 6 weeks pregnant. Since midnight I have been feeling like pressure tightness milf cramping on lower abdomen. I'm wondering if this normal? I have never experienced this early with my last two pregnancies. I also still nurse my 17 month old daughter not frequently during the day just for nap time but night she wants to nurse all night or be stuck at my boob. Could it be from still nursing? I have an appointment with my OB this Friday.
