Major cramps before BFP?

Feliece

Has anyone ever had pretty bad cramps on and off during the week before your period and actually turned out to be pregnant? Af due tomorrow and all of my tests are negative. But I have mild nausea at times, boobs are tender, and I’ve been having these weird cramps this past week! I’m sad because I just know I’ll start tomorrow, if not tonight. I just need hope...
