4 days until AF

So I’m 4 days away from AF. My hubby came home the day after my predicted ovulation date but I’m pretty sure I was ovulating the day he came home(just a hunch). Well here I am 4 days away from AF and last night after inter course I wiped and there was the lightest pink on the toilet paper. Today I’m cramping but no spotting or anything. Does that sound like af is showing up?

Update: we had sex again tonight beings that he’s gonna be gone for 50 days and I went to the bathroom afterward and there was no pink this time just super mild cramps 😬 im crossing my fingers y’all 💙💕 BABY DUST TO EVERYONE
