Hidradenitis flaring around your periods is a recognised pattern, since both inflammation around hair follicles and androgen levels shift across the cycle. Your hormone panel, including
AMH and
testosterone, came back normal, which makes an underlying PCOS-type driver less likely.
Next Steps
Please discuss this with your treating dermatologist before changing the antibiotic combination or starting isotretinoin alongside, since they have your skin and labs in full. If flares keep tracking your cycle despite treatment, consult a gynaecologist about hormonal options too.
Health Tips
Isotretinoin isn't safe in pregnancy, so please use reliable contraception for the full course and for some time after stopping it.
