don't know what to think anymore😭😭😭

Hi there! Me and hubby are ttc since  11/2016. The last time i had my fertile window and ovulated was 26-29 of january and we really did all the way😁. It's now 1 week later and two days ago i have these strange slight cramps on the side, or in the middle, upper abdomin and swollen breasts. But today i have been nauseaus a few times already and my mouth has been so watery than ever, and threw up once. I feel so bloated as well. I don't know if it's just pms which is due on the 10th or it's the one we have been waiting for. What do you think? 😫😄😇
