At the church I used to go to there was always a group of women who were pregnant at the same time, a friend of mine who went to a different church joked and said it was something in the water, her and her husband were trying for a baby with no luck at that point, I was unmarried and ended up pregnant...OOOOOPS!!! I told her I drank the water..LOL...I have grown and changed a lot since then and I remained abstinent for 2 1/2 years before my wedding night and was a single mom for 4 1/2 years..lit was tough...but anyways I am pregnant now with my mine and my husbands first baby together and there is once again a whole group of woman at my old church who are pregnant and then also at the new church I go to and one of my friends daughters is pregnant too, I don't think it is in the water this time though, I think there is something in the air...forgive me for this horrible joke but I think that the thing in the air that is getting people pregnant is LEGS!!!...LOL...no seriously I think when you are close with a group of girl your periods tend to change to the same week, you know what I mean?? If you take a group of healthy girls that all have their periods around the same time then their ovulation time can tend to be the same too, I could be wrong but that is my guess on why we get pregnant in groups...Love Meg, and ps...I am so proud of you and your friends for sticking together and keeping your babies....
