Maybe or Maybe Not

I am 7 days late as of today. I am very nervous about taking a pregnancy test. I've not been this late since December 2016. That's the month, I was 6 days late and had to be rushed to the ER because I started hurting in my stomach so bad. The doctors couldn't find anything and the next day I started bleeding worst than I ever have in my life. I believe I had a miscarriage. I hate to take a test and it be negative. I would be heart broken so I'm trying to wait it out. My husband and I have been trying for 3 years and I don't want him to be disappointed. Neither one of us have biological children. This would be a prayer answered for us both. I just turned 40 on June 29th. This would be the best birthday gift ever!!! We also celebrate our 3rd wedding anniversary on July 23rd so it would be right on time!
