excited but not sure

So I have pcos and never get periods on my own or ovulate. Iv been taking provera to bring on a period and then clomid. I was on my 2nd round but never ovulated according to my 21 day bloods. I did think I may have ovulated later though. I had an appointment with my doctor and he upped my dose of clomid but told me not to start my next lot of provera till next week incase I did ovulate later.  Iv been feeling really tired, sore back, sore nipples for the last week but I just thought it was clomid still in my system. Yesterday I went to the toilet and thought I saw I tiny bit of pink, thought I was just imagining it, today every time I went to the toilet I thought I saw pink but it was that light I couldn't be sure, but now I just went and it's defo pink on the toilet paper. Sorry for tmi but I'm super excited I may be getting my period on my own without taking provera. I'm just so happy my body is doing something at last it makes me feel like there is hope yet. I'm just hoping it gets heavier so I can take my next round of clomid
