Too soon to have these symptoms?

My husband and I are TTC .. Ive been noticing these changes or differences and Im wondering if anyone else had signs early or if in just over thinking it... Ive had to take naps in order to make it thru the last week , every day. My boobs kinda hurt but my nipples are hard , like all the time. And ive had a constant dull " cramp " for four days, it doesnt hurt just weird feeling. And peeing more often. Im still not due for a week... Thoughts?
