BFP!!! concerned mommy

i got a BFP on thursday! i tested because i figured something was up. i was having weird cramps here and there, my boobs got really sore, started becoming extremely!! hungry (not usual for me) & i couldnt stay awake for anything! i tested 6 days early so AF is “supposed” to come in 3 days. Im having really bad period cramps and no spotting. is this normal? has anyone else experienced this?

This is my first time getting a positive and im very nervous😩 i dont want to fuck up. concerned first timer!
