Pregnacy symptoms vs. Pms

I am 11 dpo af is due the 8th. I am having cramps, sore breasts, and constipation. I took a test saturday morning and i thought i saw a line and a few ladys on here said they saw it too, but my husband and bestfriend said they didn't see it, and pretty much just told me i am seeing what i want to see. Any ways i am wondering if these are possible pregnancy symptoms or pms. If i dont get my period on the 8th i am going to retest hopefully it is the BFP i have been waiting for.
