Scheduled

My sonohysterogram is scheduled for July 17. They wanted to do it somewhere between day 5-10 of my cycle but I guess that isn't happened. We can't have sex for 10 days prior to the test. I have to get blood drawn for a pregnancy test before they do the procedure which seems stupid to me, knowing that I just don't get pregnant. DH is taking off work that day to take the kids to swim lessons in the morning and I will be off to the test alone. I don't really want to go alone only because I know it will hurt and I will be all cramped up and have to drive back. I wonder if I will start having flashbacks from when I had my HSG done...
