Clomid questions! Please help.

Britney • I am a mother of two boys, ages 2 and 4. I`ve been married for 6 years to a wonderful man that I`m lucky to call mine! TTC baby 3 for 15 cycles and one cycle of clomid!
So I took clomid my last cycle days 5-9. I started spotting pink at 12dpo, then dark brown at 13dpo. Got my period at 14dpo which is 1 day late for me. It lasted for 2 days and the bleeding has abruptly stopped. It wasn't heavy flow at all but it was red. TMI but it never came out in its own, only when I put a tampon in. So now I'm wondering why my period only lasted 2 days. Is that a normal thing on clomid or should I call my doctor? I don't want to start my next round of clomid until I know what's going on and I only have 2 days until I'm supposed to. But since this was my first time taking it, I'm not sure if this is what my norm is on the medication. My normal AF lasts about 4 days with some spotting before or after.
