idk what I got myself Into

I prayed for a baby n I only tried for two months, now that I am 6 weeks pregnant and feel horrible to even to my house I don't think I can do this I want a baby but I don't know if my body can handle this stress of being sick n throwing up, in crying because I don't feel good I just feel like I'm a piece of paper just laying there I don't even feel good when I shower I just feel like dumb and zoned out for some reason should I just keep the baby? I feel horrible for even thinking this but I just can't deal with this anymore and it's been going through my mind for the past few days I just need some advice on what to do or something  
It's just I don't feel like myself anymore
