Chances of getting pregnant while ovulating???

Well I need answers to calm my nerves !! so I have been researching and trying to find answers. I had sex with my husband everyday for a week straight. I starting feeling a bit blahh, extremely tired everyday for a little over a week now and, headaches everyday, slight cramping, and feeling sick but not to the point of vomiting. As I was looking at pregnancy symptoms I came across a link to check your ovulation calender to see when your fertile. Well what do you no, that full week I had sex was the week I was ovulating. What are the chances of me being pregnant? I came off birth control about 1 month ago and we been having sex without a condom for about 10 mins then he puts a condom on. There was one time that week where he used the pull out method. What are the chances of getting pregnant off pre-cum ? got off BC a month ago, and ovulating? Please have some answers for me... has anyone experiences this and did u end up gettin pregnant? Thanks for your help :-D
