Symptom questions!!

Lindsey
Okay so I have 2 more days until I test. My boobs are so swollen especially my left one, There's more pores around my nipple, and very constipated!! I'm having the slight cramps in my lower stomach too. Everyone says that this could be your period coming on but my boobs never get this sore. Just wondering if these are really good signs or if it's just me over thinking things! HELP
