Pregnant? Opinions?

Andrea❤

2 days til af is supposed to show but i dont feel her coming at all. Ive been extremely irritable (even to my grandma which is not like me at all and she pointed it out) im crying over the dumbest things (like being cold) and ive been absolutely exhausted. I slept 13 hours today and can still barley keep my eyes open. I almost never take naps but i took a 3 hour one today. Nausea has been kicking my ass (sorry for the language) mostly at night. Ive been having such vivid dreams and for the past few days all have been about babies and pregnancy and tests. Ive been bloated alot but its not normal bloat. I feel like im pushing my stomach out but im not. My lower back started to kill me yesterday out of nowhere. Oh and my boobs are absolutely killing me. The air hurts my nipples and even my sports bra feels tight. I cant wear jeans only leggings and they feel tight also. I know i cant get clear enough respone til after my missed period but my grandma thinks im going to need a blood test to confirm since im getting super faint lines and might not produce enough hcg like her and my mom didnt either. But opinions anyone? Nothing rude please i just need some advice or input..
