Can i get a colonoscopy if i have my period at the same time?

Probably: No intrinsic reason against, save for your privacy and the GI docs equanimity, but schedule can likely be times unless you are very irregular. Call them and ask. The scope enters a different location entirely. The prep is the most odious part of this procedure for you.

Yes: But you may want to discuss this with your doctor since it may be uncomfortable for you if you have premenstrual symptoms and/or cramps.
