Similar Experiences/Advice?!?

Anna
Hi ladies! So I need some advice or info on similar circumstances. I just turned 27 and my hubby and I have been TTC for 7 months. My doctor diagnosed me with PCOS in February and I was on Merformin for a few months. It made my testosterone go off the charts and gave me severe stomach cramps so my doctor then took me off and put me on Clomid. She also prescribed Progesterone to take twice a day, prentals, extra folic acid, and a Bayer aspirin to take every day. I've been really diligent with all the medication. Taking all everyday and mostly at the same time every day as well. June was my first round of Clomid but two weeks after I had my period for four days. I was sad but took it as a good sign that I had my own period because I hadn't been having regular periods with having PCOS and high testosterone. I took my second round of Clomid this month (July) and was doing good with the rest of the meds too. Then last Thursday, out of nowhere, I got a yeast infection. This is only the second one I've ever had. First one was due to taking antibiotics after a bout of bronchitis but I haven't been sick lately. Over the counter medicine for yeast infections made it worse last time so I haven't tried any and was hoping it would clear up on its own. I also took a pregnancy test last Friday, just out of curiosity, because I've heard early pregnancy can cause yeast infections but I got a BFN. According to Glow, which I've also been using diligently for two months now, I was supposed to have my period on Sunday (July 26th) but it's now Tuesday and I haven't even spotted and my yeast infection has not gone away. Any advice? Should I make an appointment with my OB/GYN for the yeast infection? Should I take another pregnancy test? 
Thanks to anyone who responds :)
