Aspirin during pregnancy

I was admitted to hospital with debilitating migraines that had been going on for over a month. I was seen by a neurologist to ensure nothing more sinister was going on, but had no scans done due to the risk of harming bub with radiation.

She suggested not taking any pain killers for 5 days and if I feel a migraine coming on to take 600-900mg of aspirin for 3 days then to stop. I am on 2 weeks bedrest to obviously rest and see if it helps.

Has anyone taken aspirin for these reasons during pregnancy??
