When you found out that you were pregnant did your OB have you go in and get blood work done more than once. I'm confused because she wont let me schedule for my first prenatal visit but kept telling me to go in every 3 days to check my hcg levels. The OB nurse told me to go back in next Wednesday and we'll just keep going from there...... anyone have an idea why? And have you got your hcg levels check more than once?
