Low HCG levels?

Hi ladies,

I’ve had two miscarriages in 2021 and haven’t been pregnant ever since. I found out I was pregnant on DPO 9 with the faintest line ever and the line did get darker but not too dark. I haven’t tested since Wednesday as I feel like this is draining me mentally. I got bloodwork done on Wednesday and my results came in being 17 for being 3-4 weeks pregnant … on tuesday I had light spotting (literally one wipe) and it was light pink. I haven’t had spotting after that. I’m getting blood drawn again on Monday to see if my levels are going up. I’m just really worried because this is my 3rd pregnancy and none of them have been successful. What kind of testing should I request for myself or my partner. My first miscarriage was at 8 weeks, my second was at 5 weeks and i’m currently 3-4 weeks. Please advice. I just want to hear what you guys think. 😢
