Sorry about the TMI pic

So a few days ago I posted a question when my period would get back to normal being 3 months postpartum I haven’t had a period I believe I had my period around week 6 but now I’m 13 weeks postpartum and I haven’t gotten my next period and my body before pregnancy I had very regular periods every month that’s actually how I knew I was pregnant because my period was late by a week. Also when I found out I was pregnant I had a feeling I would be because the day after I had sex I had some spotting not bloody but pinkish and this morning I went to pee and I noticed this in my toilet paper, is this my period? Could it be something else? My husband and I have been sexually active so baby #2 is a possibility. Sorry about the TMI pic 😬
