Hi my name is winnie. Normally am anaemic Av been feeling lightheadedness for almost a week now I am crumpy,am not eating much cause I have no appetitewhen am dizzy I see twinkling lights on and of but the lightheadeness never stops. I had my last period last month around this time.we have a lot of mosquitos though I sleep under a net could I be having malaria or am pregnant. Keeping in mind I have had a very indulging stressful past two weeks. Is this what is causing me a delay on my period?
