Why there is a itching in vagina? does it happen a lot in pcos or pregnancy? can anyone also say what is the difference in pcos , pregnancy and periods symptoms??

A. Mummy usually PCOS or even PCOD the periods are not regular and with pregnancy the periods are not there and lastly pregnancy basically has no symptoms sometimes women don’t even realise that they are pregnant because they have regular periods and sometimes when they know they are pregnant they don’t have any such thing like nausea or anything so there is no symptom for pregnancy and for period every woman has its own symptoms or heads up that the periods are about to comeso if you’re having itching in vagina it could be associated with not maintaining proper hygiene could be urine infection vagina infection or yeast infection in that case you please consult your doctor
