4 dpo and cramping. I've got cramps, have been extremely tired and annoyed easily. I have a 15 month old daughter who has been extremely crabby, still breastfed and doesn't wanna nurse or pulls away and shakes her head no, I ask if it's good boobie and she says no. I have no clue what's up, but I really hope I'm pregnant! It's our first month trying and I am due for AF on the 12th!
