I am 44 years old and trying to conceive.. I feel very fatigued, my breasts have pains and seem fuller, nauseous and mild abdominal cramps with a pain in my lower right back..gassy, heartburn, foggy , lightheaded , at times. I had a one day period on a March 9 the and I am due for my period in a few days. Considering my age, what are the chances of being pregnant? Am I just fooling myself?
