I'm sorry, but I don't buy that a fetus is completely protected by the placenta. If that were true you wouldn't have to worry about anything reaching it during pregnancy, like certain drugs, sushi, etc. I also don't buy that parasites were always in your guy up until now. Like I said previously, most people are ASYMPTOMATIC most of their lives. But putting all of that aside for now, what is your plan? You don't trust anyone and no one in your circle trusts you. Why are you at your mothers house instead of at home taking care of your young children? They're not brainless---they know shit ain't right and they are feeding off of your hysteria. Of course they're all doom and gloom because that's how Mom is acting! You are doing them a disservice by creating so much drama around it. It's not the end of the world. You are not laid up unconscious in a hospital hooked up to IVs with a crew of infectious disease specialists poring over your medical records. You are but a speck of sand in the Sahara. WE ALL HAVE PARASITES. Yeah, it sucks, but that's life. What is your plan??
