heartbroken

my husband and i have been ttc for over a year. i was supposed to have a laparoscopy last month, in hopes to see if my husband and i could conceive. endometriosis runs in my family, and so does cervical cancer. they wanted me in early at the hospital so i could get a pregnancy test, (blood and pee). they wrote down that my pee test was negative, when the surgeon and nurse showed my mother the pee test, it was a positive. someone actually wrote down negative. but here’s the fucking click— my blood test was positive. i was pregnant. they put me under anesthesia and actually starting working on me when someone came in and told the surgeon to stop. i miscarried two days later. the last month has been awful. i beat myself up. if i just would’ve taken a test before i went.. i may still have a baby. this is my first time going through this. and ill just never know what might’ve been. i only had my mother with me. my husband wasn’t even allowed in.
