I haven't missed a period in well over a year. My cycles used to be irregular and long when my thyroid was out of whack but this last year (2016) I've got my thyroid under control and have lost a little over 75 pounds. Husband and I were not trying for a baby but we also weren't preventing it. Today was my fifth day late from my period and I thought it was odd because, like I said, my thyroid has been at a good level, my cycles have been very regular and I've been losing weight. No symptoms except very slight cramping but I thought that meant my period was coming. Also the sides of my boobs have been feeling just a little sore. Well decided to test this morning while my husband is at work and it came up POSITIVE right away!!!!!! I'm still in shock. It doesn't feel real to me. (I've never been pregnant before). And right before Valentines Day! I plan on putting the positive test stick in his chocolate box and writing "life is like a box of chocolates...you never know what you're going to get" and then giving it to him when we go out to eat or something. Holy smokes! This is crazy!!!!
