I'm 7wk 5 days and starting this week I have been dry heaving every morning and throwing up every night! Having an extremely difficult time eating anything. Last night it's like the exorcist happened and I was throwing up for what felt like hours. I have lost about 4.5 lbs since I found out I was preggo. I go to the dr Monday but getting worried the baby isn't getting enough. I take prenatals at night those seem to stay put. Any suggestions , first pregnancy and worried!
