before i blabla down there, i'd like to say that if you had no underlying condition prior to pregnancy, it probably just arose due to it because pregnancy does amplify any of the health conditions we already had, which is normal and expected. if you're taking your prenatals, it could just be something that popped up in your blood that was dormant prior to pregnancy. they'll take care of you if it's more harm than good.
here's my story with blood problems. id like to share it because its more of a miracle story with blood problems and pregnancy. i had horrific iron-deficiency anemia before getting pregnant. im a petite girl 5'2 and 118 lbs. my levels were 14 when im supposed to be up around 40-120. i stopped taking my iron medication to the point instead of twice a day it would be once every two weeks. because it caused me to be so sick and i'd throw it up so about 2-3 months prior to finding out i was pregnant, i actually was not taking any treatment properly for my down-spiraling condition. normally treatment can take months to a year or two to improve the condition i had. doctors were surprised i was still functioning the way i was. well, i went back to the doctor for a flu shot since the flu outbreak occured alot earlier this year in my community and i wanted to also see if my levels were any better since then. so they gave me my flu shot, then sent me to get labs done as usual on a monthly basis (cbc). and i got a letter in the mail of the results and they showed it had jumped from 14 to 38. i thought oh my gosh but i havent taken my medicine! three days later at 8 dpo, i took a pregnancy test due to my boyfriend suspecting i was because my usual PMS symptoms were absent and surprise! it was positive. so the increased blood flow due to pregnancy actually healed me of my anemia. i was not ever called about for my blood again and on my first prenatal appointment they took 8 tubes of blood and ofcourse my urine did not ever once call me. i went to a nutritionist to actually confirm this phenomenon and after she did blood tests, she told me my levels are very much in the normal range when they'd likely be lower at this point in pregnancy. i really have a miracle baby!
