okay so my last period was 3/22/21, on 4/23/21 I had a faint positive took a test two days later and it was dark.

On 4/25/21 I got my hcg blood test and it was 75 according to my last cycle I would be four weeks then I bled for 2 days almost like a period it stopped and I took another test and it was darker than all of them. The doctor said it was a low level and to repeat. So on 4/28/21 I had another hcg blood test and it was 220 doc said good it went up but it's still low. Then today on 5/3/21 my levels were only 283 so now they're thinking it's an eptopic pregnancy but the ultrasound isn't showing anything except a cyst that they believe raptured so the ER doctor said due to my levels she's gonna chalk it up to be a non vaiable pregnancy and to see my OBGYN in two days if my levels don't go down then they'll have to give me a shot to get rid of the tissue. Has anyone experanced this and had a healthy pregnancy? I've heard of people being misdiagnosed with a missed abortion. Could it be normal my levels are so low? Im going to put the dates and levels at the bottom. Im thinking possible im earlier than they thought idk... Someone please help me out.

4/25/21 four weeks? 75

4/28/21 five week? 220

5/3/21 six weeks? 283
