19w5d blood when I wiped.

I am freaking out! I am 19 weeks 5 days and when I wiped after going pee just now this is what it looked like. My Husband and I did have sex last night, and I went for an almost 2 mile walk this morning. Please tell me this is just from the sex irritating my cervix. I have a prenatal check up tomorrow and will absolutely be asking my doctor about this but in the meantime I’m freaking out a little. I have felt the baby move throughout the day like normal.
