I had sex with my partner twic...

[Dutches]

I had sex with my partner twice a week before my ovulation week, had sex twice during my ovulation week and twice a week before my period due date? My periods meant to come on this week . On Tuesday I had sex with my partner and the next morning I noticed some light bleeding then it came on and off throughout the day (had cramping also) I'm wondering if it's my period, and if it is I don't understand why it's different from my normal periods? Coz normally my period are very heavy especially on the first two days. I'm really confused and worried, don't know what to do. I know I'm not pregnant coz I haven't had any pregnancy symptoms
