clomid effects

I took 5 days of clomid 50mg, but I had not one side effect that every person on here mentioned. Which is making me wonder if it even worked at all. I do ovulate on my own but not very well. I did get a postive ovulation test today, so fingers crossed. My question is were the side effects that you all had during the 5 days of medicine, or was it the week after? I do have cramps today but they are the all too familiar period cramps that I get when I know I'll be starting my period in a week.
