what's going on?

P
Bear with me this might be long. I have pcos. SO, I did 3 rounds of clomid January-March. I ovulated all 3 rounds with 33 day cycles (typically only 3-5 periods a year). My last cycle was April 14th-17th. On the 27th I had a tiny bit of pink spotting and that evening got an opk that was really close to being positive but not quite, and the next day it was gone! So I don't know if I actually ovulated or not. So I just took the 27th as o positive and counted the 28th as 1 dpo (guess). On all rounds of clomid I got sore breasts nipples at 7/8dpo and they lasted until a day or two after af started. This cycle (no clomid) I got nauseas, dizzy at 8 dpo, & constipated. That carried on to about 16 dpo. Than I started getting painful breasts a day before 'expected' period and nausea/dizziness randomly. Took a test 1 day before af negative. Took one Wednesday negative. Boobs are getting more tender but little nausea now, only dizzy here and there. So now I'm 5 days past expected period and still feeling off. With my first pregnancy (miscarriage) I just knew I was pregnant. For the last year with every month/cycle I automatically new I wasn't, but this month I can't for sure tell myself I'm not. What do you ladies think?
