Alisha • Husband and I have been married for 5years, together for 7 We have 3 fur-babies and are looking to expand.
What the heck ? I also have no period signs and that's not normal for me either. I'm moody and emotional and that is it normally I get pretty intensive cramps before. I want to be so hopefull but I'm not.
