Period is late not pregnant how can I make it come ?

Hey everyone, I’m 2 days late I have a history of regularly cycle because of pcos although my eggs are fine there are no sacs or anything like that. I’m 2 days late and don’t want to be any more late because I’m supposed to have a blood test next week but I need to be on my period when it happens, and I don’t want to delay the blood test as I’m trying to get pregnant (fertility clinic asked for the blood test) Is there anything I can do like drink or massages that may help my period to come ? Usually when I workout my period comes shortly after but I really have no energy right now. My boobs are sore and I’m tired and really hungry. So I’m getting all my usual period symptoms but it’s not there. Thank you in advance 💗
