Ugh need advice

Katie • TTC for three years with hubby.

Soooo I was 6 days late for AF. later on in the evening I started spotting brown and light pink(wed). Wore a tampon for sleeping hours (5hrs) and it was 3/4 full with light pink and brown. I change my tampon whenever I pee. So yesterday (thurs) I used about 4. Some was med some was light. Now I'm spotting brown. Advice?????

Spose to start round 3 clomid Sunday... But will test before I do so.
