Should we BD at his parents house 🙊

So my husband and I are TTC and going away tomorrow for a couple days. I have a few apps, some predicting that I will be ovulating while we’re staying at his parents house.

I’ll be taking opks and if I get a positive... what should I do?? Should we try to BD secretly at night or find somewhere else? We’re going to do the deed tonight just in case but I don’t know what to do if we get a positive opk while we’re away. I really don’t want to miss our chances this cycle,

Also, they don’t know that we’re TTC.

What would you do? 🙈
