Allergy attacks symptoms and conditions

im having cough and then wheezing for a couple of minutes. My doctor thinks its common allergies, but I wasn't having my usual allergy attacks. She put me on Singular and It's been 3wks now and I've been feeling worse than ever.

I got the Kenalog shot for my allergy attacks. The first time i got the shot was in Mar. 05, i was on my period and it lasted for almost 3 weeks! i was scared because i thought i had some kind of infection even though i wasn't sexually active. Then a week and a half later i get my period again?! After the shot expired i started to get sick again and i couldn't take it anymore so my mother made me an appointment for the shot. This would be my second time getting this injection. I got my shot Aug. 25, 05 and i was less than a week away from getting my period but when the time came for period to come, and it didn't!!! Now im really scared because im sexually active, but taken pregnancy tests and came out negative and, no period yet!!! If this has heppened to anyone else please i would to know what your story is and if you were in the shoes as im in and any other information related to it, Thanks!!!
