This is getting ridiculous!

3 days from AF and getting nothing but BFNs since 9 DPO on a 28 day cycle. All the time lines & symptoms line up perfectly. My breasts have been so sore since 7 DPO and have only gotten worse. With my last two pregnancies, that was the first & worst symptom. I can't lay on my stomach, can't wear a bra nor NOT wear a bra, it's driving me crazy. For years they start getting just a little sore no more than 48 hours before AF. The test I took this morning was "invalid". What is getting me down so bad is I have always gotten a BFP well before AF is due (7 DPO with my last pregnancy). I'm starting to guess im out this month. Top pic-11 DPO & bottom pic-9 DPO
