First Pregnancy Paranoia...

My husband and I just started TTC this past month and to our shock-I'm pregnant. We didn't expect it first try. I'm about 5 weeks 5 days, and Google scared the crap out of me last week. I already have anxiety, so I shouldn't have ever done that! My symptoms are normal, fatigue, sore breasts, mild cramping, minor back ache, constipation, etc., I never had spotting, but I keep getting so scared something will go wrong or is wrong. Not sure when morning sickness will kick in...? Everyone keeps telling me it'll be fine, but it's natural of me to worry!! I just really worry that it was so easy for us to get pregnant, there's no way pregnancy will be this simple. I've been trying to keep myself busy at home, I just hate how scary the Internet can make things seem!!! Sorry for venting!! I know the worrying isn't good, just wondering if I'm the only one!
