Hello and welcome to HCM,
Conception or
pregnancy does not take place during
menstruation, few days before or after menstruation.
Thus, the chances of conception or pregnancy are negligible.
Tiredness, nausea and light-headedness are probably not associated with menstruation.
Tiredness, nausea, high sense of smell and light-headedness can be due to flu or
common cold.
High frequency of urination can be due to
urinary tract infection (UTI).
I suggest you to consult your primary healthcare provider for clinical assessment and urine examination.
Common cold if present can be managed by anti-inflammatory and anti-allergic drug.
If any infection is present in urine, it will be detected on urine examination.
Urine infection is also treated with antibiotics.
Thanks and take care
Dr Shailja Puri
