My period is late

Rheannon
So my period is 4 days late but I'm not sure if I should take a test or not as I suffer with in regular periods and I don't know if my tablets worked when I took the last as I had 2 weeks of spotting after my last period. I've been trying for 14 TTC months and don't want to get my hopes up what do you ladys think? I also suffer with pcos x
