I barely had any symptoms... usually, when I was PMSing, I used to get bloated, gassy, crampy, etc.
But the day I got my BFP, I realized I couldnt pay attention when people were talking to me, because I felt like I was falling asleep anytime.
Also, I never realized, that a few days before everytime I brushed my teeth, I gagged.
I stopped eating chocolate (which is strange), I would get full inmediatelly whenever I ate.
I would go to bed earlier (10pm instead of midnight), and my boobs soared, but when I used to PMS, my boobs used to soare really bad, this time, not so bad, but I still feel it.
Good luck!
