Could Oversized Uterus Indicate Twins?


Dear Midwife,
I am 15 weeks pregnant with my first child. I regularly see my OB/Gyn each month but he hasn't measured the size of my uterus yet. I have been reading several pregnancy books and they say that at 15 weeks my uterus should be easily felt 3-4 inches below my belly button. My stomach feels hard starting at my belly button, but I'm not exactly sure what I'm feeling.

I also started feeling my baby move during the middle of my 14th week. I read that if you've had more than one pregnancy or if you're thin you will be able to feel the baby move sooner but I am overweight. Could this be a sign of twins? What does a uterus feel like? Is my uterus larger than it should be?



It is kind of hard to describe what a uterus feels like to someone who is inexperienced, as there are lots of other things in there that can feel similar. If what you are feeling is in fact your uterus, then it is possible that you are off on your dates (it is possible to have a period, especially a light one, while you are already pregnant), or that you have twins.

There are several other possible explanations as well. You don't mention what your provider said when you asked him/her these questions, so it is a bit hard for me to know for sure what is going on. If you didn't ask your own provider these questions, I'd really advise that you do so. Your provider is the best person to put your mind at rest.
