TTC #1 - Husband Overseas

MrsJohnson • Married💍 RN🏥 Expecting Baby Johnson September 19✨
Hello ladies!! Happy Holidays! 
New to Glow but love it thus far and the support of the Glow community.
TTC #1 while visiting my husband this month overseas in Finland. My fertile window is dec 25-31 with highest day on the 29th. Just so happen I fly back to the US on the 29th. Any suggestions to make sure they stick haha? This is "practice" day #3 this week for TTC :)
Won't see him again until march or may 2015:(
