I'm 21 weeks pregnant and have been taking iron tablets prescribed by the Dr since 16 weeks. I still feel awful so I went back and got another blood test. Just phoned to check the results and the receptionist said the Dr has requested a follow up appt regarding my iron levels. I can't get one till Tuesday which is frustrating as last time they just left a prescription at the desk. Do you think I've been asked back because there's something more serious going on or is the doc just trying to let me down gently that nothing is wrong I'm just pregnant!
