confusion and nervousness after a loss

i'm scared of every thing when it comes to this baby. i have all the typical pregnancy symptoms...constipation, headaches, heartburn...and then i have asthma and anxiety like crazy. there are drugs i could take. there are herbs i could take. some say the drugs could cause complications, some say the herbs can cause complications. so which do you choose.

i've always leaned towards the natural side of things, but the naturals haven't been tested in pregnancy like the drugs have...i found a heartburn tea this morning...but it contains marshmallow root...a herb that has had contraindications...but to what extent? if i have a cup a day would it be ok? would it be better than a heartburn drug?

i want proof. which is better. i'm tired of opinions, i need proof. i can't be blase about the health of this child when i've already lost a child. every thing is so confusing. i know a lot of people who take raspberry leaf and it's probably safe, although i've seen studies where they have found that it may cause uterine contractions. so who's right? who do i believe?

you would think that with something like pregnancy, that's been around since, well, almost forever..people would know and there would be proof, that this list is ok, this list is not. where is that list? and if something is bad for pregnancy, why are companies allowed to continue to make such products and promote them to pregnant moms? i'm just so confused. and i don't like being a basket case.
