Sex spotting & confusion.

K

Hey ladies,

I'm feeling super confused. My period is due in 4 day.

Last night we had sex nothing rough. And this morning there was bright red blood this has turned to brown through out the day.

Is this just the start of AF. Could this be something more serious? Or perhaps an early symptom of pregnancy?

I'm trying not to over think it. But would love someone else's opinion.

Thanks in advance x
