Menstrual cycle is the reproductive cycle, if a woman is fertile she is always on her menstrual cycle. I think you're asking if menstruation smells, there is a smell but it shouldn't smell bad - maintaining good hygiene prevents odour, also avoiding unhealthy menstrual products such as tampons and commercial sanitary pads will prevent bad odour too.
Maintaining hygiene during menstruation is not much different to maintaining hygiene at any other time during your menstrual cycle, contrary to common belief menstruation is not dirty or unhygienic. Wash daily with water only, and use appropriate menstrual products like pads, tampons or cups. Be sure to change your menstrual products at appropriate times, even if not full tampons and pads should be changed every 4-6 hours and cups every 12 hours.
Research so far shows that it has a potential benefit in maintaining healthy cholesterol and also to play a role in premenstrual syndrome and menstrual cramps.
Hygiene in general is important to stay clean and healthy. During menstruation menstrual flow can change vaginal pH and menstrual flow can also be favourable to bacterial growth so maintaining hygiene and managing flow is all the more important. During menstruation poor hygiene can increase risk of bad odour and vaginal infections, also not changing tampons often enough risks TSS.
Well good hygiene for that is to wash the vagina everyday to keep it clean. Be sure to change your pad every time you go to the restroom. If you use a tampon remember to change it out every 4-6 hours. Always keep the pubic area clean and wash your hands after changing your pad/tampon. Hope that helped
