Hello. From January 17, I started hormonal contraception -drovelis. I saw a gynecologist at 9 DC because I was concerned about persistent post-period spotting. The doctor prescribed me this medicine as part of my therapy. I took the first active pill 10 DC. After 2 days of taking the tablets, the spotting stopped. The doctor told me that for this month the pills do not protect me, so we use a different protection with my partner. I took the 18th pill today. Until now, the mucus was thick and creamy. Today, however, it has become stretchy, pouring and bloody, a bit like spotting. I understand that since I took the first tablet at 10 DC, the cycle has moved by these 10 days and I should get bleeding while taking placebo tablets? However, is it possible that the bleeding will come earlier? Should I be concerned about this staining? I will add that for three days I have been taking the antibiotic clacid 250 g because of a cold. Please help.
