I starting the 5 day loading phase of creatine monohydrate on sunday which is 4 times a day,however i was unable to take some on tuesday,does this mean I have to start over again and start on day one or just continue until friday which would be 5 days on taking it?,then after that its onto twice a day

Don't sweat it. The idea of the loading phase is to save time in getting enough creatine in your system to start to matter. Even if you just started out with regular daily doses you would eventually get there, it would just take longer.

so does this mean i can start my dosage again tomorrow until i have 5 days worth in my system, which would be friday?

Yes.

I'd just go ahead and finish the five days, then go to normal daily doses on Friday as scheduled.

You could take another round of loading doses on Friday if you want, but it's really not necessary. The creatine will build up in your body over time either way. :)
