Side effects after ovulation using clomid?

Lucy
I have been ttc for over two years and my doctor just gave me clomid at the beginning I did not have side effects at all great but now my nipples are sore and I feel bloated and my body feels like am going to get a cold I don't know if it is pregnancy systems or what I would hate thinking am pregnant then later to find out am not what to do ??? Please help anyone...
