#1.Is baby asprin safe while pregnant? My dr seen risks of high blood preassure on my ultra sound.#2also a diff dr said I have hyponatremia what do I do

Yes. Baby aspirin, 85mg, is definitely safe in pregnancy. Hyponatremia, without any other disease processes going on, would be very rare in someone your age. This other doctor told you, you had low sodium but didn't tell you why? Unless you have renal disease or a host of other conditions one wouldn't expect in a 22 yr old, i think you're likely ok. Talk with md about it so you can be informed.
