I was diagnosed with PCOS in February 2014. From then on, I only had my periods in March, April, July & September 2014. In November, I spotted on 16th & 18th November 2014. The blood colour was brownish and it only filled a little bit of my pantyliner on the 16th & just a little bit of my pad on the 18th. No more blood after that. Please advise. Thank you.
