I had my last period on February 7th. I had unprotected sex on February 18th and 20th. Then, starting on the evening of February 21st, I experienced rust-brown bleeding with a texture similar to a period, but it was not very frequent. The bleeding continued for the entire day on February 22nd, was completely painless, and did not require a sanitary pad. It disappeared by Sunday.
I have always had a regular cycle, and this is the first time my period is late.
Now, on March 11th, my period has not arrived. I took a
pregnancy test early this morning using Prega News, and the result was negative.
Please suggest the next steps.
