Sore breasts are a side effect of the Clomid. In fact, Clomid gives you so many pregnancy symptoms you cannot base anything on how you are feeling.
You usually ovulate 7-12 days after the last pill. It can make you ovulate late.
Hi I took clomid for two months and I am now 8 weeks 3 days pregnant! my first sign was sore nipples, I had no other signs (other than a little moodiness and fatigue) untill almost 6 weeks, but I had heard that clomid can make your nipples sore, so I didn't think much of it untill I got my BFP 12 dpo. Good luck to you let me know how it goes for you. What dpo are you?
