i had a medical abortion about 2.5 weeks ago, and about 2 days after i took the 2nd pill i noticed it became difficult for me to breath. i am very short on breath and am very fatigued, its also hard to sleep and i do not feel well rested when i wake up. i went to my doctor and my oxygen levels were very low. i was 86 then after walking for about 40 seconds my level was 76. my doctor couldnt believe it so we did it again and i started at 77 and my level then dropped to 66 after walking for under a minute. i had a ct scan and he said it was normal also my lungs sounded clear. my blood work showed i am not anemic. any ideas as to what it could be? i m trying not to become anxious however its hard not to be. I am to the point where I am yawning just to get a full breath of air.
