im going to makkah in a couple of days can i preform when im on my period or is it haram
No its not haram, the prophet said you can preform it but the only thing you can't perform is Tawaf.
No, i don't think so. You should probably use one of those pills by which you can delay it.
You'd get a more accurate answer if you specifically addressed this to some fellow Muslims I think...but given that the Quran teaches that women are filthy as they menstruate, and men are to consider them unclean...I would take a guess and say there may be a restriction based on this...but not 100% sure.
The only thing that isn't haram is worshipping your god, everything else is haram.
Yes you can but you can't perform Tawaf. Have a safe journey.
