Yes my periods are always irregular my LMP was july 28th however i took 3 positive pregnancy text on 9-13 so today is when they said it appears im 6 wks.... I do have an ultra sound scheduled tomorrow at tge hospital they said to keep the appointment...it worries me because its a free clinic until I recieve medicaid. So im not sure it will be different... how far along were you when you heard your babies heart beat?? Did you have any pain at all?
