Lower pelvic cramping


What have been some of your first pregnancy signs prior to even testing? I'm 10 dpo today and just afraid to even test for the let down. For 3 days my nipples have been sore, slight temp, headaches and very low pelvic cramping. I still just know I'm gonna get a bfn and I think over the past 3 days I just keep telling myself it's just my messed up cycle causing these symptoms. What have you all experienced?
