5 days until AF due and

I get really upset and cry everytime I get what resembles a cramp, I worry that she is coming early. I had very light pink spotting for 2 days Sunday through Monday which were a week-ish after AF. I don't want AF, I want a BFP that's all. I'm so stressed and consumed over the TWW that it is causing panic. I am 33 and my bio click is rocking. Between SO and his low sperm count and my BMI I doubt we will get there. I feel so emotional and lost. 5 more days. I feel broken.
