Clomid extending period?

Becka • Student and stay at home wife. Currently TTC baby #1. Starting assisted conception in June.
This is my first cycle of clomid 50mg. I am taking it cd 3-7. Normally my period lasts 4-5 days today is cd 5 and I am still bleeding. Not enough to fill a regular tampon but not my normal cycle flow for cd 5. I'm wondering if anyone has experienced this before?
