Hello) I had a smear for chlamydia today at 21 weeks, as my analysis was lost, it was very painful, came home, after going to the toilet, I see that blood clots are coming out and bleeding slightly (is this normal? Is it from damage to the mucous membrane? Has anyone experienced this... or should I go to the hospital?)
