Last night i went to the Emergency room for terrible cramps. They did blood work and everything came back fine. They changed my due date to may 2nd. This was my 1st ultrasound. My OB doesn't see people until after 8 weeks. So im 5weeks and 5 days and they told me that they saw blood in the gestational sac.. i need to go back in 3 days for an other ultrasound if there is still blood they said i will be starting with injections... has anyone gone through this??? This is my 2nd baby but with my 1st i never had any complications.
