hmm band 41 is not very lyme specific. it is specific to spirochetes, but not specifically lyme, so with those results it's not 100% sure.
HOWEVER, since you seem to have had a positive lyme test, then yes, it is possible to have passed it in the womb
/www.scientificamerican.com/article/mothers-may-pass-lyme-disease-to-children-in-the-womb/usually a short course of antibiotics will make the bacteria much more visible to the immune system than before abx. repeating the test a few months after the abx can show a more clear positive than what you have now.
my lyme specific symptoms really showed their ugly head after an aggressive course of antibiotics for ... h-pylori. So not related to lyme, but the antibiotics were active against lyme too and in the right amount, so they provoked a reaction and started more specific symptoms. Before that i had allergies, asthma and very bad stomach issues and pain in the upper right of the stomach (duodenum), i've lost over 20 pounds. I've done dozens of tests and nobody would be able to say what was causing my pains. Some said h-pylori (had negative test), some IBS. No other lyme symptoms. After the abx, the symptoms started.
