So I'm trying a new dr this pregnancy as I have a 7 month old currently and I didn't really like my dr last time. According to this app I am 10 weeks 2 days. This new Drs receptionist didn't schedule me until I'm suppose to be 15 weeks. She didn't ask any questions she just said oh so you think your pregnant how about we schedule for this date. Didn't ask about lmp or how far I thought I am. I'm just worried. Isn't there like blood work or something we need done before then?
