Discharge

So my boyfriend and I had sex last month and i don’t really remember the situation but we were worried that I could be pregnant. Since I take the combined pill I researched about it and realised that it was a very slim chance. It had already been my period so I was waiting till my next one to see if I was pregnant or not (depending on if I missed it). I’m due to start and I’ve had some cramps and discharge today but it more browny white (sorry if it’s tmi). Could this discharge mean I’m pregnant?
