i had an emergency visit from the midwife yesterday. all weekend i was suffering a severe headache and blackouts. i phoned my optician who said my eyes have been tested not long ago so to phone my gp who as i am now 16 weeks told me to call fetal assessment. the midwife came around checked my bp which for the first time was normal and my blood level is low but not dangerous so all ok. with the headache ive got to have paracetamol every four hours for the next two days to prevent them. also got to go back on iron tablets. the wonderful thing was she listened to the heartbeat and the placenta and alls well though my placenta is low but that may move. what happens if it stays low? also can you use karvol when pregnant? as suffering with blocked nose at night such a pain cause its all dry!!
