YES that is a concern! Platelets help you clot. Less clotting=more bleeding. Sometimes extreme bleeding. Have you ever heard of HELLP syndrome? Hemolysis, Elevated Liver enzymes, Low Platelets. Symptoms of it mimic many common complaints of pregnancy. Do you have any idea why your platelets were low? Was that the only abnormal lab?
Does low patelets mean the same as low hemoglobin? I have low iron/hemoglobin due to a genetic anemia, that can only be impacted so much by diet. However, in pregnancy iat the end my iron gets quite low. So I take floravit/floraditx (herbal iron) which is very effective, as well as regular iron supplements. this time around I've had difficulty tolerating the regular iron so my midwife recommended Feramax, which bypasses your stomach and gets absorbed very easily. Its got a lot of iron in it but doesn't constipate. I felt the difference within a few days. I'm not sure if its available in the US yet, but maybe you can get something similar. I tried calling some stores in the US since I live on a border town but they didn't have it.
Just eating healthy food will not fix low platelet count. Same for herbs. Low platelets may have many causes. Also, everything is matter of degree.
You are in danger of bleeding. You need to see a doctors, have a blood test and in depth discussion.
