Hi, I am kind of lost here, last month and the months before that, I was having really sore breast, but that may because how I was on the depo needle for 10 years but I have been off now for 1 year and a month so things i was told were back to normal, well then this month so far my boobs have not been hurting at all, I was told my ovulation date were June 22 to July 2..I did have sex around the 1st or 2nd of July, i'm suppose to get my period on July 10 or 12 somewhere around there, is there anyway I could be pregnant and not know it yet?, I have no real signs yet..only no sore breast but I was told that if I was pregnant my breast would be tender but not everyone is the same right..

Please if you could give me some sort of answer that would be great
