Im going crazy 👀 asking Googl£ 😒 anyone else experiencing this during pregnancy. . . should i be worried?

Long story short im 5mnths preg my friend is around the same . lets say she is 6mnths 3weeks apart.

I just began having shortness of breath it feels horrible, cant breath so good like im in a small space with lil to no air im not used to this at all.

My friend just checked out from hospital. A week ago she was out of breath comes to find out about blood clots that almost killed her could've traveled to her head or heart im glad she is ok. They put her on blood thinners.

I myself was on baby asprin aka blood thinners... In the beginning of preg. Even before i conceived. It help me stabilize my pregnancy i kept mc before but finally 5months baby looks healthy , now im worried if the same scenario my friend went through i will too...

I pray its all in my head but this is new to me feeling shortness of breath for the first time & cant breath to good. Any one else feel this symptom ? When is it a red flag. . .
