Early signs? Please comment :)

   I stopped taking my birth control the beginning of January. It took a little bit, but I think my body is finally getting back in a kinda regular cycle again. Glow says my fertile window just ended. I do think ovulated based on my CM. I had sex 3 time during that period. He pulled out, we know it's not reliable, but if we get pregnant then we would be thrilled so we aren't super stressed about it. Anyway, yesterday I noticed that my boobs seem HUGE, and a little sensitive. This happens right before my period, but I still have 2 weeks until AF. Also, my SO is a smoker ( I know, he's trying to quit!) but yesterday the cigarette smoke smelled so strong to me! It's not a smell that normally bothers me, i never even notice it as he doesn't smoke around me, and I guess I've gotten used to the smell on his clothes.. But yesterday it was so strong and so gross! I feel great otherwise, no cramping, spotting, nausea, or anything like that. Could these be signs? I only ovulated last week so I'm not sure if it's too early to feel anything??
