Trying to get pregnant

Soooo I’ve been trying to get pregnant... we had sex the first day of my fertile window and in the middle of the week was ovulating and a couple of days after

Soo now it’s one day before my period and I don’t feel no signs of my period I always know when it’s coming

I’ve had a headache for the past two weeks and I would feel cramps here and there but I’m so confused I don’t wanna get tooo happy and then my period comes any advice ☹️☹️😩😩!!
