Hey guys! So my cycle has suddenly changed on me and I’m no longer my regular 31-32 days… my last period was 6/7 and lasted 5 days. I got my positive opk 7/3 and bd that morning and the next morning. I still do not have my period and have tested negative so far.. the only symptom I’m having is my nipples seem to be bigger and darker and stick out more and hurt as well as a deep ache in my breasts but they aren’t tender to the touch. Am I still testing too soon? I’m just so lost since I’ve never had irregular cycles and here I am. Any one else experience this symptom and get a bfp?
