Yet another thing

So my last resort is this fertilty cleanse me and my husband will be doing for a month. The only problem is a week after the cleanse we’re going on a family trip to Florida and the room is booked for all of us. But how do you get busy on your one ovulation day with the possibility of your family being present. I’m just so discouraged. I want to quit so much and my husband won’t let me and it just makes the whole process more painful for me.
