It's rare to not get a positive on a urine test. Once the HCG is high enough it is detectable on a urine pregnancy test. When women don't get positives when they think their period is due, it is usually because they ovulated later than they thought.
Case in point is my youngest daughter. After my miscarriage I had no idea when my second period would come since it took forever to get the first one. I kept testing and testing and finally got a faint positive on the 42nd day of my cycle. Sure enough I had ovulated late.
Breast changes will be different for everyone. Women usually get tender, swollen, achy breasts before their periods, too. If you are pregnant the tenderness can last the entire pregnancy or just a few months. Just depends.
im 15 weeks pregnant and my boobs are still some what sore. i knew i was pregnant when my boobs started hurting and that would have made me 3 weeks preg so i knew i was preg even before i took a test. they have hurt off and on some days more than others. theyve grown too..i was an A cup and about to have to go to a C cup and im only 15 weeks preg! its kinda awesome! haha
The first time around, mine were super sore for the first 3 months. This time around - if I am in fact pg...will test this w/e when AF is due - they are quite enlarged....and tender, but not truly sore.
sorry ... after about a month or two they should stop aching... try rubbing....... lol. i got cut off the rest you got
the sorness in your breast should ache for a while, but i would have to say the sorness should stop after about a y rubbing your breasts with warm water. and changing positins in how you sit can effect it too.
