My period is not heavy like usually is. My period came one day laTE.

Periods will often be one day, two day even a week late. They are seldom always perfect.

Periods will vary in flow often.

AT this point nothing points to anything but normal. Do you worry or have fear of some other issue?

Yes that I'm pergnent because before my period came I was gassy nausea and with headeache. I had sex but he came through my butt
