I'm 30 weeks and my 14-month old isn't walking yet.  She's 28lbs.  I picked her up tonight and it felt like someone knifed me in the uterus.  I couldn't stand up straight for a minute.  Is this that round ligament pain that I've read about? I get the kicked in the crotch pain but this was a new feeling.  I'll ask my OB at my next appt and will for sure call if it happens again but thought I'd ask y'all since this isn't your first rodeo.  Gracias!
