Question...

So my period was the 5th 6th and 7th it was very wired. medium on the 5th, barely anything 6th , and one gush then nothing on the 7th. Well today the 9th I have light pink a couple times when I wipe. Is it left over or is something else going on? Me lower tummy is very sensitive had a miscarriage in the middle of March. This is my second period since. I have been having sex using pullout method.
