So fuckin upset

I'm writing this as I'm in tears. Found out i was pregnant on the 19th went in that monday and it was at 6 went. Back two days later it was only 8 but no bleeding or cramping. Made me come back in yesterday to have my levels checked again and got called this morning and theyve only went up to 11. Not only does this devastate me but infuriates me bc they want me to come back in next week AGAIN to have them checked and see the dr this time. It pisses me off so much bc why the hell are they still making me get my levels checked for a 4th time if theyre barely moving at all? All theyre doin is reminding me that im pregnant with my baby thats not growing and im not gonna be able to carry and deliver. They said they wanted to send my blood work off to another place to evaluate it bc sometimes theres factors in there machines that may or may not pick something up, idk im confused. Asked me if im bleeding. And i continue to tell them NO no bleeding no cramping and she just doesnt understand why if the baby aint growing. This was suppose to be my first baby, my first everything, and my fertility dr is making me continue carrying it instead of trying to figure out whats goin on. And worst of all today is my step daughters 6th birthday and as much as i wanna be excited for her all i can feel right now is numb and shattered! Im devasted!
