So I'm not trying to conceive but I do keep track of everything to avoid it all, but I'm 7/8 dpo and today I been having lower back aches as well as every cigarette I smoke I gag on it and feel so nauseous straight up thought I was going to puke. It's not like I smoked a bunch or anything, I'm only less than half a pack a day....anyways should I be worried?! My boobs have gotten way bigger, super bloated but nothing else I been feeling lately. Do I need to take a test, what do y'all think?? Af due the 8th --
