A little nervous

My bf and I were having sex when I heard a sound like my insides were gurgling. He then asked me if I was ok because he felt like he was hitting something inside me. I didn't feel any pain but I could feel him hitting something. We repositioned assuming it was my cervix and was fine for the remaining time. After my tummy felt very strange like something was moving around in there.. Shortly after I used the restroom and experienced a tingle (like when you loose your virginity and pee after like there was a cut...) and started bleeding like I started my period.. Even though I was just on my period 2 weeks ago. The flow is very light. Im not sure what's going on but we are both very worried. Tried googling but you know how that goes... Any advice would be awesome..
