Last 2 days I have had slight drops in my bbt and dull cramps for like 1/2 hr in morning yesterday thought for sure AF was showing her face soon. I temped this morning and it’s creeping back up. I am 11dpo and 2-3 days before AF. Could the dull cramps I felt yesterday at 10dpo been from implantation??? Later into the evening my breast pain got almost unbearable and that is unusual. I could feel them throb just sitting on the couch. Yesterday at 10dpo i took a test and it was negative. Only other possible symptoms I really have at this time is runny nose, slight nausea when getting out of bed or laying there awake, and very crazy vivid dreams(sex dreams) and a dream I got a positive test. Any insight is appreciated.
