They said it's easy to get pregnant after a miscarriage yet AF comes knocking on my door.

I thought it was easy to conceive after a miscarriage. I swear I felt pregnant. I had been cramping for about six days which felt like round ligament pain. I was so certain I was pregnant. And then AF showed up a day earlier 😔 im wishing it is implantation bleeding but I guess not. Why was I cramping for days (only happened once in my life during my last pregnancy)
Ladies, how do you get by each month not waiting for that countdown till your period after ovulation? 
How do you cheer yourself up when AF shows up? 
I'm sad
