Seriously, why argue with someone about religion? I am religious but if someone isn't I don't hold it against them and I definitely don't argue with them or push my beliefs on them, first of all I am not going to change their minds nor are they going to change mine and I hate when people push their religion or lack of it on me so why should I do it to them.
As for the OP, glad to hear they have nailed down the cause of her problems nd that they aren't extremely serious. I wish her all the best and congrats on the baby.
