Hi I hope i am posting in the right section

I have taken clomid this month (50mgs) O day was on the 28th (i have a 35 day clycle) and so that makes today 3 days past O. I am feeling really really crappy, have every single pregnancy sign possible, feel tired, bloated, heart burn, sore everything - but i know its not possible to be pregnant as yet as its only been 3 days!! I also take Metformin 2000mgs a day - Is this a normal reaction to the clomid? or is this a PCOS symptom? I am going out of my head as i would love to say wishful thinking and its infact implantation but have been through so much to fool myself like that.

Please helP!!!!! i feel really awful right now
