its all started 3 yrs befor. My periods was good from the start and suddenly i got spotting on my period date instead of bleeding usually my cycle lasts from 3-5 (good flow for 3 days). i consulted the doc and she asked me to take blood test and Scan. She told its Hormonal imbalance due to over stress and she asked me to take Modus and after 7 months of regular monitoring and consultation and medication i got periods on cycle which lasts for only 2 months. Mean while i got married and again the problem started with delayed period and now the doc( not same doc) she told PCOD and i have taken sidha medicine and now got my cycle (30-35days) my cycle is regular for 8 monts but still couldnot become pregnant and when i go for follicular monitoring on dec 2016 she said i have BILATERAL PCOD. confused by this term. May i know what it is all about, is it different from PCOD and what should i do further.pls guide me
