Immune system and hormones

Jen • I'm 34 with b/g twins via IVF FET, born 11/2016. Had a mc after first IVF/FET, 3 failed IUI, mild endo. 1% morphology
Has anyone experienced a weakened immune system while taking Femara/letrozole and Ovidrel/trigger shot? I've had swollen glands for the better part of two months now. Ended up getting strep throat after being that way a couple weeks, took antibiotics, was fine for a week or two, and now I have it again. This is very unusual for me, so I thought I'd see if anyone else has had a weakened immune system from hormones. I know stress can do that, but I haven't felt stressed lately.
