Hi, I am 7 weeks pregnant and have been nauseous for the past week. This morning, I felt so sick that I thought I would give into the nausea and throw up. I hovered over the toilet and started to feel that gagging feeling you get from deep down when you vomit, but nothing came up but saliva at first. After several times of dry heaving, I noticed 2-3 small specks of blood with the saliva. I have not had any vomiting or blood since. I talked with my OB but she really didn't provide any guidance. Should I seek medical attention immediately? Could this affect the fetus?
