can anyone help me please

Hi so I'm on day 35 of my cycle. I took provera to bring on a period and then clomid. I had day 21 bloods but they showed I didn't ovulate. I think I may have ovulated about 4 days later. But that's only I guess, I may not have ovulated at all.  Last week I had really sore nipples and they were big and red also some cramping. So that was about 4 days after I think I ovulated. How long should I leave it to test again and start my provera. This is my test from this morning and it's negative
