Ttc for a year

My husband and I have been ttc for a little over a year now with no luck. I was diagnosed with pcos a couple of months ago. My doctor put me on metformin and provera to start period. Then on cycle day 3-7 I took chlomid. I started using the opk on cd7 and it was low on cd7 and cd8 which is expected. On cd9 i tested at peak which I thought was was early but I was excited to actually get a peak reading so we dtd. I used clear blue advanced so I couldn’t test for 48 hours after the peak. So on cd11 I decided I would test again (it wouldn’t hurt). It was low on cd11 and cd12. I thought ok maybe I did ovulate. So on cd13 I didnt test but after reading some posts yesterday I decided to test again this morning on cd14. It is reading high?! Is this normal? I have had really bad heartburn and nausea the past couple of days. Any insight will help! TIA!!
