Anyone else?

These last few cycles have been very strange for me and I’m wondering if anyone else is experiencing the same thing… been ttc for the last few months and leading up to when Af is supposed to be here, I’ve been experiencing all the pregnancy symptoms, extremely sore breasts, gum bleeding, nauseous, heartburn, headache, slight cramping, back pain, smelling everything, and then when AF is late, BFN! Last month I was two weeks late, this month 2 days late, slight spotting but I know it’s too late in my cycle to have implantation bleeding and still BFN… What is going on with my body! Prior to these last few months my cycles have been pretty regular! Anyone else feeling strangeness happening??
