Headaches. Some women do notice more headache in early pregnancy than at other times. Women who get migraine headaches may find they are more frequent in pregnancy, or may have them less often. Non-migraine headaches may also increase.
The blood vessel changes that lead to fainting may contribute to this symptom. Certainly some women get headaches on the oral contraceptive pill, so there may also be an effect from the hormones directly. And don’t forget that stress may tend to give you a headache. There may be several reasons for feeling stressed. Being pregnant could be one of them.
So to relieve these headaches you might want to try some form of relaxation (such as resting, yoga, meditation, listening to a relaxation tape, massage— there are many ways to do it). If the headache is severe, or you are worried by it, it would be a good idea to see a doctor to check that there is no other cause. If you want to relieve it with medication you can take paracetamol (for example Panadol) in the recommended doses (one to two tablets, every four hours as necessary, up to a maximum of eight tablets a day).
