TTC advise

Ok Mom's out there...

My husband and I have decided to TTC. I had a conversation with my friend today who is pregnant (hopefully still she's afraid she may have had a miscarriage this morning at 4 weeks) although we both hope that she is still with child we got on the topic of Do's and Do Not's of pregnancy such as string cheese, coffee, uncooked fish etc. But what about the Do's and Do Not's for TTC? I am 28 and this will be our first time TTC I've never been pregnant before and she got me thinking about if I'm making the best choices while TTC. so other than the obvious no alcohol and drugs what are some lesser known things I/we should look out for? Best wishes to all the ladies out there who are anywhere in there life be it trying to avoid pregnancy, your first pregnancy and especially to all Mama's whether or not their babies are on Earth. Love to you all.
