I began having allergic reactions around the age of 15; however, after much testing, it seems as though I wasn't allergic to anything. So, my doctor sent me to many specialists - to no avail. No one was able to diagnose my problem. I charted the food I ate, the time of day, the activities I was doing all at the time of these reactions. The only thing that was the same throughout was that I was in the process of my menstrual cycle (whether it was during, right before, or right after). Since then, the only time period that I didn't have an allergic reaction was during the time that I was on birth control pills. I've recently had a miscarriage, and during the pregnancy I had 2 "allergic reactions" (one 2 days before I found out I was pregnant, and one a few days after the actual miscarriage). What could be causing these allergic reactions?...or is it these allergic reactions that are causing my problems with conceiving a child? Please help!
