Hi Marit,

!!!!
Very exciting to get a

- you must be very happy!!
Well, I haven't heard anything about the baby aspirin affecting TSH levels. I take it early in the IUI cycle as a blood thinner and to help the uterine lining during cd2-cd10 (when I was doing injectibles), but the nurse had me discontinue it after the IUI. I am not sure if it has another purpose later after pg also. Definitely a good question for RE or endo dr. to be sure!!
:gl & hope you have a wonderful pg!!
