Hello! I had a protective intercourse on 17th and my significant other finished in the condom, after pulling out. I was due for my period on 20th but I still haven't got it. Note that I started a few medications for my acne and severe rosacea on 18th which include Cardivas(to help with less flushing in the facial skin), Dazit M, and Involym. It's the 27th today and I still haven't got my period. I don't think I could be pregnant because I have often faced irregular periods since the past one year . However I'm still not quite sure what is causing it. I'm also traveling in the coming month and I really want to get done with my period asap.
