Pregnancy related. Clinic now?

I had PCOS for which I had taken treatment of Ginnette 35 for 6 months on two occasions 2 years ago for hirsuitism though my periods were always regular. Now I am trying to conceive since August last year. In October I had symptoms of pregnancy like enlarged and heavy breast, nausea, increased urination. So, I took pregnancy test by kit. And it was faintly positive and then I had period which was just 2 days postponed. Then again I felt as if I am pregnant in this January. Took test at 26th day of my cycle and it was really very faint, difficult to notice. So, I repeated the test next day. Though I was feeling as if my symptoms are disappearing and my test was much more fainter. After 2 days I had period. Difficult to say if it was a normal period or an early miscarriage. I never had PMS and my symptoms felt so real. Am I having progesterone deficiency which is causing miscarriage? Should I wait for 6 more months or visit infertility clinic now?
