Bleeding after baby dancing

So guys I have no idea what's going on. I had my nexplanon removed February 28th. I had 3 days of spotting april and may. Then had bleeding 8 days in may. Nothing in June besides 2 different days of spotting. Hubby and I baby danced last night and a few minutes later I felt something so I wiped off and had bright blood. I put a tampon in and woke up and when I took it out there was hardly anything there. When I wiped after peeing there was pink spots but that was it. I took a hpt on the 29th and bfn so idk what is going on. I had no appetite all week til yesterday my daughter's 3rd birthday and I felt like I was starving. No pains or anything.
