Girls, hi everyone) quick question — has anyone had light pink discharge…

Girls, hi everyone) quick question — has anyone had light pink discharge at 12 weeks? I have just a tiny bit for the second evening in a row. I went to the hospital; they checked and the baby is fine and overall everything is good, they also checked on the exam table and everything looked fine! But I'm still worried because my belly is also aching a bit. If anyone had this, please share, maybe you know what's up?
