Asprin at 22 weeks

Hi,

Has anyone been prescribed 75mg of aspirin during pregnancy. I was told today to start taking one baby aspirin a day.

This makes me nervous as in a previous pregnancy I was taking this from when we were TTC and I miscarried at 10 weeks.

In previous pregnancy we were advised this by fertility specialists.

It may not be why I miscarried but I'll never know.

The reason I was told to start taking it now was to prevent blood clots just because I've turned 40. However everything has been done so far with tests and they said my age isn't an issue.

I guess I'm just nervous from past experiences so wondering if anyone has had similar experience.

Thanks
