Are Extremely sore nipples with clomid normal?

I know it says sore breasts are normal for clomid, but I took my last dose 3 weeks ago. I'm not exactly sure when I ovulated this month, I usually O cd14 like clockwork, but clomid was messing with my opks and I have no clue how many dpo I am now. But my nipples hurt so bad. I've never had nipple pain as pms before, so idk if it's early pregnancy or a side effect of clomid. Any insight is appreciated. Also I took a hpt and got a bfn today. So maybe it's too early.
