Cd 13- positive OPK?!?!

Brittany • Mama to 2 girls! 💗 🤰🏼 with number 3!
I dipped my wondfo stick into my cup and was shocked to see 2 lines ! Then I followed up with a digital to be sure .. Got a smiley. Holy crap! I usually don't get positives until CD 18/19. I was on a steroid for a rash I had.. Could that have affected my cycle ?! I can't wait for my husband to get home !! 😁
