Femara/Letrozole sisters, please help!!

I have PCOS. I started my first cycle of Femara/Letrozole 7.5mg a day after two failed cycles of Clomid. I took Femara on CD 2-6. My period lasted few days longer than usual this cycle - 9 days with brown spotting on CD 7-9. Had intercourse on CD 10 and started cramping few hours later. When I peed there were streaks of fresh blood mixed in with discharge/semen. Is this all normal? What cycle day should I expect to ovulate? Been TTC for two years. Any advice you may have?

Thankyou for your time. :)
