I am also on my first cycle of Clomid and had the same question as you. I didn't get any side effects prior to ovulation, but since the day I ovulated I've had sore bb's (was just my nipples, now all over) and since about 5DPO I've been going to the toilet twice every night (annoying!). I know that these are both preg signs, but was worried that maybe the Clomid had caused it and didn't want to get my hopes up. I'm now 16DPO and have had 2 BFN but still no AF. So I'm still quietly hopeful, but don't really know what's going on. (I've booked an appt with my doc for Sat in case nothing happens before then.)

It's frustrating not knowing what to blame, isn't it?!
