Need advice!

Brittany • Mommy to 2, Miracle baby #3 on the way!

So my husband and I are going to visit his family this weekend. I will be 5 weeks pregnant at that time but his family doesn’t know, nor does mine. We aren’t saying anything till I’m over 12-15 weeks but my issue is that I’m so nauseas and tired all the time. I’m exhausted to where I wake up and want to go back to bed right away.... I am nauseas all day and nothing really helps at all. His family wants to take us on a boat but I know I’ll get sick.... ( no excuse there cause I’m in the coast guard on a big ship so sea sickness I don’t get...) well I don’t know what to do or say if they suspect anything. Any help would be great!
