I know that some cramping, especially in the very early weeks of pregnancy is normal, but I'm almost in my 10th week os my second pregnancy and have been experiencing uterine cramping several times a day every day virtually since implantation. I've talked with my Ob/Gyn about it, and he's prescribed me magnesium supplements that I've been taking for 3 weeks now. I'm still cramping! I'm not bleeding/spotting, and u/s shows the baby is doing just fine. I'm drinking plenty of water, but admit that I'm not getting much exercise since a normal walk to dd's school is enough to cause more cramping. I'm trying to take it easy, but this is really aggravating! Has anyone experienced this before and did it go away after the first trimester or do I get to put up with this for the rest of my pregnancy. Any tips??? I'd be so grateful for any input!!!
