I'm nervous

Okay so I'm in irregular cycles (71-86 days) but this month I tracked my ovulation and I had TWO very clear positive ovulation tests on Cycle days 24&25. I'm currently 8 DPO and of course it's Christmas soon and my SO's birthday is on the 27th and I want to surprise him if I'm pregnant as he really wants a baby, as do I.

My boobs have been really sore and I've been having weird "twinges" I guess in my abdomen. I had sore boobs for the first time ever last cycle and got my hopes up but I can't remember if it was this far away from my cycle due date. My next period is due on January 12th and my last period was November 2nd- 7th. My fingers are crossed! 🤞🏼 I'm going to test in 6 days💖😵

Baby dust to everyone!
