Period Smell

Is there any ladies when you are on your period your vagina smells bad....not fishy....but not how it normally smells...I know it’s because of the blood...but I’m wondering is it something I’m not doing right when I’m not on my cycle not eating right or exercise or enough water intake....I’m not sure but it has me feeling really down and self conscious, especially with me living with my boyfriend (he doesn’t say anything crazy)...If you have been where I am can you give me tips to I guess lessen the odor?
