maybe baby??😍

So I'm 17 days late. I've already taken a test and that was negative a couple days ago. But I've also had a weird thing going on with my tummy. I'm SUPER gassy (as in I should probably invest in some air freshener buttplugs or something😭😂) I've been having gross poops for about 4 days now and I'm nauseous as soon as I wake up. And honestly the only thing that helps with it is to smoke but I can't smoke all the time! My period is always pretty consistent and right on time. I haven't been stressed out or anything either🤷🏼‍♀️😩 I looked up "not so common pregnancy symptoms" and there's one that says that sometimes the woman will get a stuffed nose and I do! It started about a week ago and it's only in the morning. And then my stuffed nose goes away 🤷🏼‍♀️ any help would be appreciated! (Yes my husband and I are trying for a baby so fingers are CROSSED!)
