IUI and prednisone.

Manda • Ttc since 2013. Fertility treatments at CNY fertility January 2016. 3 Timed intercourse with letrozole. BFN 1 IUI bfn. IVF 1 transfer BFn 6 frozen. FET#1 2 transfer BFP (2 stuck, 1 split) Triplets BBG
So this month were starting <a href="https://glowing.com/glow-fertility-program">IUI</a> after 3 unsuccessful timed intercourse cycles. I'm taking 5mg Letrozole and they just added 5 mg prednisone. Anyone know exactly why they use this steroid? The nurse said they just like to use this medication with <a href="https://glowing.com/glow-fertility-program">IUI</a> but a steroid it does have quite a few side effects. I have hypertension controlled by medication but this can effect it also blood sugar levels can be affected. I have insuline resistant PCOS. Anyone have good results with the medication?
