I should test right?

Hi ladies! I posted somewhere else but I was hoping I could get opinions from some moms and soon to be moms. I was supposed to start my period on the 12th(give or take a couple days) and before that I had what I thought were my usual pms symptoms(sore boobs and cramping) but period never came. I still get slight cramps here and there nothing too bad. My boobs stopped hurting except for Thursday I woke up and they were sore, but now my nipples are kinda sore but I only feel it if my bf squeezes them slightly. I don’t really have symptoms. I had Alfredo a couple nights ago, and got a huge wave of nausea but it went away once I laid down and then Thursday night I felt slightly queasy. I had fish sticks and tator tots but couldn’t finish my food til later tht night. I haven’t really felt sick since then either. I did have this discharge that was kind of creamy yellowish color. I know it’s been a week since AF was supposed to arrive and I obviously should test, but this would be my first time so I’m not sure if what I feel is pregnancy symptoms or if my period is just delayed(haven’t been sick or stressed really). I’d love to hear how you guys felt during your first couple weeks and if you think I have a high chance and a positive test! Thank you guys!
