Confused!!

Melissa.

Unfortunately, I went to the ER today after months of trying and finally getting several Positive PT on 7/11/18, I started spotting brown on 7/14 woke up today 7/15 with red blood, went to the ER knowing something isn’t right. The doctor told me there urine test was negative and the blood work HCG levels were on the low side an 8. And tht my uterine walls were thick. And tht I possible could have been pregnant and could have miscarried, to go to my OB in 2-3 days to recheck my levels. I feel like the doctor thought I was a lier I’ve taken dozens of test and they all came back positive. I’m an devastated and utterly confused in why HPT could be positive and there’s negative? Why is this happening to me. Has any one gone through this? Is there any hope?
