Week 27 almost and I'm still throwing up every other day, not sleeping, starting to get anxiety (I have anxiety attacks even before preggo) short fuse, my back hurts especially my tailbone and low back area. On rest per doctors instructions due to high BP and not to be on my feet long or lifting anything so that results in me being at home alone. I know a lot of women say that pregnancy was a breeze so I'm curious.... Am I a freak of nature? Oh and I'm in tons of pain under my left breast due to coughing and sneezing and vomiting, I feel a rib is out of place. I feel so weak... Could that just be from vomiting constantly? Any of these symptoms ring a bell to anyone and do you think I should go into the ER? Heartburn is eating my insides I feel also! I'm a mess I know but any feedback would be appreciated. Don't know how I'm going to make it three more months
