Expanding Uterus?

Today I woke up with a lot of nausea and cramping.  I meant to take Diclegis last night but I forgot.  The cramping was kind of painful and I swear I actually felt my uterus expanding.  I thought you couldn’t really feel or tell when the baby is growing but maybe you can.  Uterine cramping is because of the uterus expanding so maybe the baby is growing and pushing it out.  Either way it only lasted a very short period of time.  My friend wanted to hang out today but I felt so sick I didn’t really want to go over to her house.  I convinced her to come over to my place.  I made hummus and tuna melt sandwiches for lunch.  Then we went for a walk at Lake Balboa Park.  Her visit really did end up making me feel better and my nausea went away.  I showed her the videos of the baby and we made plans to hang out later this week.
