My first one was supposed to be at seven weeks but I had a possible eptopic so I went in at 6 and a half
I went as soon as I new I was pregnant but when I found out I was 17 or 18 weeks and didn't no so glad I didn't no I was pregnant x
Call your Doc. and make an appt. I called to make an appt. right away but my clinic here schedules the first appt. at 10 weeks, so It might be different for you where you live. I took my prenatal right when I found out. Imo, the sooner the better for both.
My doctor recommended that I wait for my first appt until I was 8 weeks, so that the baby will be big enough to find on an ultrasound. And yes, it is never too early to start taking prenatal vitamins.
