clomid side effects?

bridgette
hello, so this is a weird question so bear with me please! 
I'm on day 2 of clomid (50 mg) and ever since I started taking it my nipples have been very hard/erect? and I have had sore boobs.. is it normal to have this nipple side effect? I'm a little creeped out 😁 hoping it means it's working though lol
