Whether you choose to disclose the journey that you and your partner are about to embark on is a very personal decision, and whether you do so is up to you as a couple. Having this conversation before any awkward situations arise avoids any miscommunication and will make sure you're both on the same page.
On first thought, it may seem completely unnecessary to talk to your boss about such a personal problem. But over the course of the next several months, there may be many mornings where you need to come in to work late because of monitoring appointments, or take a last minute day off to fit in an IUI or IVF procedure. Keeping your boss in the loop (presuming you think he will be supportive of your need for flexibility) can make those last minute schedule changes a lot easier.
If you are concerned that your boss may hold this against you or not be supportive of what you are going through, don't feel obliged to tell. Your clinic may be able to provide you with a generic note stating that you are having a medical issue that requires frequent appointments.
Your Family and Friends
There are going to be times when you may need extra help over the course of the cycle. You may need a ride home after a procedure or some help food shopping if you are on bed rest. There are all sorts of little things that come up, and having family members or friends on board can ease some of those worries. Close friends and family can provide emotional support as well by giving you an extra shoulder to cry on or person to vent to — who isn't your partner.
You'd be amazed at how many people struggle with infertility or know someone who has. You might be surprised at some of the people who open up and share their stories with you.
Taking these steps to prepare for infertility treatment, and hopefully a pregnancy, will make it much easier on you in the long run. Getting healthy and staying healthy for a pregnancy can seem like an overwhelming task. The thoughtfulness that you put into readying your body is important, and will help ensure that you and your partner are at your peak readiness for your pregnancy and new baby.
