Spotting Every Day in Second Trimester

Has anyone else experienced brown or pink spotting every day during their second trimester? I’m 19 weeks today, have had two ultrasounds because of the bleeding and our little man is healthy and active, but I have bled a little every day for the last three weeks!

I asked my doctor about incompetent cervix a couple weeks ago. He gave me a pelvic exam and said everything feels fine. Three weeks ago he gave me a 7 day course of vaginal clindamycin for BV and last week he gave me 10 days of cephalexin for a bladder infection. I’m almost done with the cephalexin and still spotting some each day.

I go in for another ultrasound on Monday. Has anyone else had this happen?!
