10dpo and AF due 12/21

I ovulated late this month (also the first month I got a +opk). we BD'd for 3 days before mt opk, twice the day of my opk, twice the next day and thwn for 2 more days. One app says AF due 12/21 which is right on track with my typical 28 day cycle. Glow says AF due 12/23. all last week I had twinges of pain in my lower abdomen, vivid dreams, tired, boobs are kind of sore (I have a hard time with this one- I've never had sore breasts but thwy aren't super sore, just if I push on them). yesterday I had very very very light spotting only when I wiped but today I have cramps like AF is coming. I've been super emotional about the subject, I can literally cry at the sight of someone pregnant or announcing their pregnant. I have been taking hpt just to torture myself as they have all been negative. I think I'm out this month ladies. i was so sure this was going to be my month, it will be devastating when AF comes. my fiance tries to understand but he doesnt get my heartbreak. baby dust to all who are hoping for a Christmas surprise.
