Does cramping mean I didn't conceive?

Capri • I`m 25, from a small town named picayune. Me and my fiancé are trying for our first baby!! I`m in love!!
Well I'm trying to conceive my first baby and I started using glow last month!! I'm due for AF 4/4!! But today I started having some mild cramps no spotting or nothing yet! Today is the day that I'm suppose to take a HPT but I'm thinking maybe I didn't conceive cause of the cramps!!
