I don't get my period regularly and i was wondering, could that be a big factor as to why i'm not losing any weight when i exercise?

Yes: Some women are pre-disposed, genetically, to a condition called PCOS which is associated with insulin resistance, obesity or overweight, and infrequent or complete lack of periods. Also can be associated with unwanted hair in areas such as nipples, chest, breast and chin. A great way to lose weight is to use an app like MyFitnessPal as it helps track calories in/out. Most lose weight that use

Well,.....: In "Medicine", everything may be connected in some way. For example, if your periods are irregular, you may have an underlying thyroid disorder, and the underlying thyroid disorder would be more likely to cause you to have trouble losing weight, etc. Get a good examination and history from a caring doctor and you may be able to get to the bottom of your issues. Good luck.
