Sorry this is a long question but in the month of feb I started my period on the 5th-8th than I had sex the 19th and 26th. I was supposed to start my period again march 5th but didn't. I had sex again march 12th. And the next 2 days I bled but it was light and I don't know of it was my period because my period is never late and never short and not usually a light bleeder. I had sex again the 18th and 26th. And I bled again even more lightly April 8th and 9th. All the sex was unprotected. Could I be pregnant?

You could but we can't tell you if you are over the internet, why have you not taken a pregnancy test yet?or have you?
