Is It Safe To Have Kenacort Triamcinolone And Progynova For Irregular Periods?

Hi Doc,I have consulted my situation with my Obgyn. My period is not really regular, and I am willing to have a baby soon. My period record is unstable for the last 2-3 months, e.g.: I got the 1st day period on November 1, and just got it on January 5. Being treated with my Obgyn, to have a baby, with my period condition right now.. He asked me to consume Kenacort Triamcinolone and Progynova (one tablet each / night). I hope next month, it will get positive. My question is, is it safe for me to consume such medicines? Is there any suggestion? Thanks. Mira
