What’s going on???

I’ve had some gas pain since 5dpo & now I’m 8dpo & am having some period like cramps and i don’t usually get them until first day of period. I’m not due for AF for another 6 days. I know it’s too early to test but has anyone else experienced anything similar & what were the results? I’ve also had some lower back pain but it’s nothing crazy along with boob soreness since 4dpo
