Period 2 days early - Stopped after 24hours, now slight spotting

Hi all,

I really need your opinions!

I have a 28 day cycle ( 7days long always), has always been like clockwork since I first got my periods at 14. I’m 26 now.

I had unprotected sex with my partner the day before ovulation, my « period » came early (2 days before it was due) and it was accompanied only by very light cramping (usually I cannot do anything but lie in bed on day 1) and it was still enough to fill a pad, but much much lighter than usual. Then after 24 hours it stopped and I just had light spotting when I wipe (firstly pink and now rusty but it has basically stopped completely now).

I feel very bloated and gassy, my breasts are tender but not very sore.

Did I get my period or could I be pregnant?

Thanks for all your help!
