TMI PICTURE: WHATS THIS

So I recently had a baby in September. I bled until about the beginning of November, then I started my first period since having the baby on November 22 and it was a normal period. I bled for about 6 days. Today, I went to go to the bathroom and i noticed light pink blood on both of my thighs. Then, I wiped and there was a dot of red blood and then wiped again and saw this (picture). Is it part of my period? Usually when i’m done with my period, no blood comes after.

Me and my husband are having sex if that question needs to be answered and no, we don’t use condoms, he just pulls out. (As we are married we are fine with whatever happens) But, I just had my period so obviously i’m not pregnant. I just wanted to throw that in there. But what could it be?
