Normal cycles with abnormal bleeding?

Angel
I have seen 2 OBGYNs in the past year, and I didn't like either of their medical advice. I liked them as people; they were nice. But after talking to people, I feel like I should see someone else. 
 
Here's my story:
 
I have been off the pill for 2 years this November. My husband and I have been TTC unsuccessfully since February. I have 28 days cycles. 
 
Sounds normal so far, right?
 
Well... I start spotting 2-7 days after ovulation. For 5-7 days. Then I immediately start my period. Which lasts for 7-8 days. I bleed for an absolute minimum of 13 days each month of a 28 day cycle. And 2 OBGYNs showed no concern and wouldn't do testing.
