I need help!!!

Toni
Today I leaked & thought it was my monthly & I checked in the restroom & there was a mixture of brown discharge .. few hours later I use the restroom again & discover chunky off pink discharge. It's been a week since I had unprotected sex he pulled out but befure pulling out like a minute before I did have a feeling he came in me but I guess not ! I'm really concerned I have 4 days until my ovulation window closes.. any suggestions or opinions?? Thanks love 😘
