Cramping before period is due

Ann • 👼🏻👼🏻👼🏻🤰🏻💑 3 angels no live babes but hoping this pregnancy turns out different. Married to my babe of 7 yrs ❤️

I’ve been having a lot of sex during my fertile week.. as I’m trying to conceive and hopefully this time actually get a healthy living baby out of all this (I’ve had 3 losses.. 2 mc and 1 stillbirth at 6mo..)

So my period is due in a week and half.. I’ve been cramping for days on one side.. could this be from ovulation? Conception?
