Labs/bloodwork

[Ked2267]

Needing some advice. Im getting labs done soon to determine my state of health and what all is causing my spotting before my period. But about a month ago I got terrible poison Ivy and had to get a steroid shot. Since then it’s completely messed up my cycle, making it come later and now the bleeding won’t stop which is different from what normally happens. Will the steroid totally skew my lab results enough that I should wait until my period goes back to my “normal”? Or will it not really matter? Thank you and I appreciate your suggestions!
