Pelvic Rest on Anniversary

Br
Today my husband and I start our anniversary/babymoon trip. We have 4-5 nights at a beachfront hotel and plan to spend the next few days exploring San Diego and spending time together. 
Unfortunately, I also had my anatomy scan today. While baby is doing just fine, I appear to have a low lying placenta. I've been put on pelvic rest... Some timing. 
Of all the things I've found myself worrying about over the last 20 weeks... It never even occurred to me to worry about this.
