Bleeding at 4 weeks??

Hi! This was my first month ttc and I had been testing starting at 8dpo and once I got to 11dpo still getting a negative I came to the conclusion I wasn’t pregnant and decided to stop testing. The very next day at 12dpo I started having mild cramps and spotting, it felt exactly like my period but it was 2 days early and had a gut feeling so I took a test that night and got the most faint positive- I could’ve believ it and assumed I was experiencing implantation.
However over the next two days the cramping and bleeding got worse and I was passing clots so I called my ob and was told it sounded like I has having a miscarriage but on the third night of bleeding I started vomiting so I went to the ER
They did an exam and I was told my cervix is closed so it might be a threatened miscarriage however I’m worried about it being ectopic because I’m taking pregnancy tests every morning and they are gradually getting darker which I feel like if it was a miscarriage that wouldn’t happen right?
When I went to the er I was 4 weeks and my hcg was at 23 and also way too early to see anything on an ultrasound so I have to get more blood tests to see if it rises or falls.
Today is the 5th day since the bleeding started and the cramps are gone and hardly bleeding anymore, I’m only feeling little twinges in my uterus more so on my left side but I get them in the middle and on the right sometimes to. and the pregnancy tests are still looking like they’re slowly getting darker.
Playing the waiting game is so hard does anyone have any similar experiences?!
