Question: My girlfriends period came on the 26th days and flow for 3 days Could it be implantation bleeding or period
Answer: Hi 
The question is did the period come at the time she usually gets it
If it did then its most likely her period 
Periods last for about 3  5 days so thats normal

If you are worried that she might be pregnant kindly get a pregnancy tests done 
Thanks
