So my first appointment isn't until the sixth. My uterus is three finger widths below my naval and I'm only 12 weeks. I have had four previous pregnancies so I realize my uterus will grow slightly faster. I am a fraternal twin and twins run in my family (mother's side) any twin mommies conceive without drugs and not find out until second trimester. My other thought was fibroids... any ideas, advice, or experiences please share. I'm going nuts.
