Aspirin is no longer recommended in situations like yours. This is based on evidence collected recently on 95,000 patients. Taking aspirin by women increases the risk of haemorrhagic stroke by 7 per cent and decreases the risk of ischaemic stroke by 24 per cent. However one does not know exactly who is prone to haemorrhagic stroke and who is likely to get ischaemic stroke. Hence, I think it is better to avoid its use.
