Help!

🎀🎀

I had positive tests about 2 weeks ago. It seemed like they were fading lighter and the lines were going away and I started bleeding so I assumed chemical as I’ve had them before and I quit testing before the lines went completely negative. My period was lighter but spotting last after for 2-3 days which has never happened. Now I’m having lower abdomen soreness almost like a pulled muscle right down at my uterus. It almost feels like a tugging or stretching and pressure. Do you all think there is a possibility I’m still pregnant? Has this happened to anyone? Could this be ectopic?

I plan on going and grabbing a test later I just want some input until I’m able to get there. If I were still pregnant somehow I would be 6 weeks on Monday. I don’t remember if I felt this with my first.
