Am I?

Hello Ma'am. I saw your yt video about how to prevent pregnancy. If you don't mind helping, can I ask you a questions?

I have a 30 days cycle. I had my last menstruation period on Feb 14-17. I need to count 30 days from my menstruation period til I get 16days right? To check my ovulation. So my ovulation would be on Feb 29. Unfortunately, I had unprotected sex on Feb 22. So I had to take TRUST PILLS on Feb 23. And I had withdrawal bleeding which lasted for 2 days only (first day, March 1)

Now, I had unprotected sex on March 4. is there any chance I can pregnant here?

Or, my bleeding in March 1. Is my new period? It's March 20 right now, and still don't have menstruation
