What the heck is this???

Sarah • 31 & Married 4/27/19 💑💍 Mommy to a beautiful baby girl! PCOS & hypothyroidism.

I'm estimated 6 weeks and 2 days. Just went to the bathroom and when I wiped, had this.

My husband and I did have sex 2 days ago. Is this just semen mixed with old blood or something else?
