My period was a no show..

Nat

5 days late my period has been completely missed now, no signs of having a period at all but when I take a test it looks negative to me.. idk what is going on o.o my last pregnancy I didn't know I was pregnant until a month or two later. My fiance says he sees a line on the one text, and thinks im pregnant. From the mood swings, to my complaining about my boobs being sore and feeling like they're growing, my complaining about lower back pain, my complaining about a pressured air like feeling in my uterus or a pinching tightening feeling in my belly button, and being insanely so much more horny feeling. Also with the nausea, puking, headaches, and always being tired... idk
