Really need insight!!

I really hope no one has experienced what I’m about to go on about, however if you have I am so sorry, and I could really use some insight.

I was 20 weeks pregnant and my baby boy Stetson, and he had Nonimmune hydrops fetalis, he passed away at 21 weeks and 4 days, I delivered him 4 days later on February 4th, 2025. So it has now been exactly 4 weeks and 1 day since I delivered him.

(Husband and I started having sex again exactly 1 week after I delivered-please no judgement-I felt like it helped me cope) anyways,

2 days ago(on Monday), I took a test to see if the hcg was out of my body, the test came back positive-showed up very quickly. I then called my OB and they had me come in yesterday for blood work, which that came back at 4.84, I took another test yesterday, it was the same as the test from Monday. I then took another one this morning, and it is darker than the ones before. I need help.

(Also, I used second morning urine with all tests, all the same brand.) and the test I took this morning I barely even got per on it and I thought I had wasted the test until I seen the line show up darker.

Please help 😩
