Sore boobs?

I’m 5DPO (early) but I’m experiencing the worst breast pain EVER! I normally have tiny pains a day or two before my period but THIS! Anyone else experiencing or experienced this with a good outcome? 😭 Also, last night I couldn’t sleep for the life of me and 4DPO and today I’ve been having cramps that almost feel like period cramps but I’m ALWAYS regular.
