I have been having some very light pink blood this week only on toilet paper when I wipe,I thought it was a Uti at 1st but have no systoms of one I have one in passed,I called OBGYN office & they said it was most likely period spotting I'm suppose to get Depot shot again soon,I did have unprotected sex Sunday with husband was kinda of rough so I didn't know if could be from that also? So could it be implantion bleeding,period spotting,uti, or from rough sex? Thanks
