Hi so im ttc #1..
I am over 3 wks late and i finallyyyy have an appt w my obgyn today. I have taken 7 hpts all negative one maybee vfl but it was a blue test soo i dont trust it.
I want to be a good advocate for myself today bc i neeed answers..
Im guessing they will do a urine test.. But i should make them do a blood test right? Can i ask them to do an ultrasound to see if they see anything? 
Thanks in advance
