Going crazy trying to figure out what's going on!! Please help!

So I got my period on the 3rd and me and my husband had sex on the 2nd, 3rd,5th,6th. On the 7th my period started to lighten and then it stopped. Well yet again we had sex on the 7th and I had light bleeding/spotting. Woke up on the 8th and the bleeding/ spotting finally stopped. Well today I got a little aroused and I went to the bathroom and wiped and I am bleeding /spotting again. We had unprotected sex everytime. What is going on could I be pregnant or implantation or am I just broken:(??
