Okay so let me explain my situation
I had unprotected sex on the 24th of June
And I had already had my period for that month
Then I started bleeding on the 29th it was on and off
First it was pink then it got heavier then light and it stops and then comes back
Could I be pregnant.

ANY time there is penile insertion you run the risk of pregnancy. No form of birth control is 100% effective.

While it doesn't sound like you are, you will have to wait a couple of weeks after your period is due to take a test.

It sounds like you are concerned about being pregnant. If that's the case, then why are you engaging in such risky behavior. Since you posted in Child and Teen health I assume you are a minor. No one should engage in sexual intercourse unless they are prepared to have a child.
