Dont know what wrong i am doing....Periods cramps or pregnancy ??

Ladies, I am doing every damn thing to get pregnant...I track my ovulation using digital opk, record bbt, taking prenatal daily and zinc supplements, hubby on multivitamins, sonography done to check if things are normal ( tilted uterus found which shouldn’t b a problem but no other issues), making sure to bd 4-5 times in fertile window, used conceive plus gel in last month, daily pray to god to bless me with baby.... I am yet to get my AF on 16-17th March but since today morning I am feeling exact abdominal cramps that I get in PMS. So this means I will be getting my af in 4-5 days ( generally this is the pattern)

I don’t know why I am not getting things I want...everytime have to cry and reset my feelings to achieve those two pink lines. I am 32 yrs and ttc baby 1 but don’t know what wrong I am I doing or god doesn’t want me to b happy !! Sorry for this but I was vvvvvvvvv hopeful this time as did everything I understand to get pregnant!!
