Possible miscarriage

I was estimating I was 7 weeks pregnant on Tuesday. I woke up that morning and took my daughter to the eye dr. While I was was waiting, I felt like some discharge was going on. The longer I stood there waiting, the more I felt it. After about 20 minutes, I went to the restroom and saw that my underwear was soaked through with blood. I immediately called my ob to see if I could get in. Mind you, I hadn’t had my first appt with them yet for this pregnancy. I wasn’t scheduled for that for another 2 weeks. They fit me in a couple hours later. The bleeding had tapered off by then. They did an vaginal ultrasound but couldn’t see much except that my uterus was in the condition for a pregnancy. They did blood work to check my hcg levels and wanted me back in 2 days (today) to check the levels again. Well I’ve had very minuscule spotting yesterday and nothing really today. I still haven’t had cramping or anything but I have felt lethargic like I typically do with my period. I went in to do more blood work today and they said we should have a better idea tomorrow when they can compare to hcg levels. I’m so anxious to know what’s going on. I didn’t really have any pregnancy symptoms before all this started so I can’t say that I “don’t feel pregnant anymore”. If anything, I feel more like it now because of the lethargy and little bit of nausea today. I’m trying to stay positive but I just don’t know. Any thoughts from y’all?

Update: I got my results back from the blood work and my hcg levels went up! Still not out of the woods but I’m scheduled for an ultrasound on Wednesday and hopefully we see something 🤞
