after my ectopic and losing part of my left tube,it's been a challenge to conceive. i calculated i was supposed to ovulate 10/08/11. had intercourse on 10/05/11 and 10/07/11.i started cramping,on my good side

, and spotted a little after sex on the 7th,but then the bleeding stopped. i researched some,and found it could have been ovulation spotting,but i'm not sure because i've never done that before. what could the spotting have been? and what do u think my chances are i will conceive this month? any opinions are appreciated. thanks so much!!
