The lunch meat thing really shocked me, as my boss looked at me like

when she saw my lunch from Cousins one day. So, I looked into it and sure enough, there's some chance of bacteria which is harmful for a fetus. Of course, you can always heat up the lunch meat and make a melt. Just puttin' that out there.

Soft cheese is a no-no, too. Although I found myself eating some
delicious red wine cheese spread at a party one day... oh, one fine day.

The heart rate thing is I'm sure for the baby's sake, as well. You're not supposed to get overworked/overheated, which made me wonder about the pregnant lady I saw getting a suntan one day...

The no fish rule is not a rule. Doctors suggest
limiting your fish intake to a couple times a week, but not eliminating (there are some hearty omega-3s in there to say the least). Certain types of tuna are okay as well as fresh water selections. Basically, you want to stay away from fish that have a higher potential of carrying dangerous levels of mercury (like shark,
really, people?) I also stay away from sushi (not that I'm a
huge, huge fan) Rare meat, doesn't affect me because again, I'm not a huge fan. But, the harm is that undercooked meat carries the potential for food-borne bacteria. Everyone knows that. Skin creams, I've heard that some are harmful; if, for example, they have some kind of anti-zit hoo-ha in there (sacylic acid, I'm thinking?). I just make sure to use more natural products on my face and I do use the same moisturizers for my body that I've been using. Hair dye, my doctor poo-poo'd. I think I asked...
twice. Still says "no." There
are more natural/less-potent options but at this point, I wonder if I'd even be comfortable bending over the tub to rinse all that off. :/ I still use nail polish...
and np remover. Exercise, um.. you're
supposed to exercise even while pregnant, unless your doctor has you on restriction for a good reason. She should know better than anyone here. But yeah, I was encouraged to exercise; at least walking as briskly as I can. Even ellipticals were okay'd by my doc. Swimming is another great one, too. Perfect for pregnant moms, actually. Exercise can aid in labor pains (supposed to help one have an easier birthing experience if you exercise regularly) Pepperoni and whole milk I hadn't heard of. Since being pregnant, I've ordered nothing but pepperoni pizza (if I'm ordering pizza, that is).
Basically, I think it's safe for some things in moderation -
not everything though (some things are absolutely off-limits, like smoking and liquor). This is my first time being pregnant, so obviously have not done things "perfectly," though there is this strong desire to. Like, oops, I forgot my prenatals! It happens. But, don't get psycho over these rules. I mean, unless you want to.
