Pregnant?

So im about a week before my expected period, and ive been having these weird stretching/pulling sharp stabbing pains down on both sides of my ovaries/fallopian tubes that ive never experienced before. It seems to worsen when my bladder is full and i need to pee. (But it doesnt hurt when i pee). So i know its not a UTI. Ive been also peeing alot more frequently, and also when I do go its a very small amount. My breasts ive noticed are also getting tender.  Im curious as to whether the pulling pains im having could mean implantation.. or what. So far I have no bloody dishcarge that could mean implantation.. but i also know that some women dont bleed.  I should also add that my husband and I have been actively trying for a baby. What were some really early pregnancy symptoms you had? Confused.
