Unable to conceive. My irregular period?

Dear Doctor, We are married for last 11 months. We are trying to conceive for the last 6 months with no success. I have irregular periods due to pcos. In March my period did not come for 70 days. After marriage my cycle was never this long. During this 70 day cycle, from around 45th day, i started having severe white thread like discharge which i have never experienced before. This white discharge would come with period like feel. After around 65 days urine pregnancy home test came out to be negative. I consulted a doctor and she prescribed primolut n thrice a day for 3 days. 11 days after the course, i started getting red thread like discharge for 3 days followed by normal period. After this doctor prescribed 3 cycles of ubiphene 50 mg for 5 days starting from second day of period. Today is 26th day of my first cycle. Whether this tablet will regularize the period? If period did not come this month is there a chance of pregnancy or is it due to my irregular period? Thanks in advance
