Give me some hope 🤞🏻💕

So as of today I am 6dpo but for the past 2 days I have been having cramping in my lower back and very achy sharp pains in my pelvic bone. Anytime I sit or bend over I get this sharp pain. Has anyone else experienced this? I've also had VERY sore nipples since 2dpo. I've read this can be from the progesterone. My boobs feel heavy but are not sore. I was just wondering if anyone has experienced anything like this and got their BFP? Also what was the soonest you got your BFP? The wait is killing me. I wasn't gonna test until Friday which will be 9dpo.

TIA!
