Bleeding/spotting

Amanda

Ok so its been 11 years since I was pregnant last...... my boyfriend and I had sex earlier today and when I went to the bathroom after there was a mucus pink blood when I wiped. I’ve gone to the bathroom once’s since and there has been a little bit of pinkish blood when I wipe. I put a panty liner on and nothing is on it...... I have a little bit of lower back pain just an annoying pain nothing sharp or anything..... does this sound normal?
