The stress after a BFP!

Teri • wife...mother...stepmon...business owner... trying to stay sane while doing it all!
Okay so I got my BFP on 1/28 had my first obgyn appointment yesterday 2/4 and I'm about 5 weeks along due October 5th but I'm so stressed I watch everything I eat no smokong or drinking I've even lost 4 lbs since I found out because I have been eating super healthy not starving my self or anything, everyday I'm praying for a full term pregnancy and healthy baby. Is anyone else experiencing more stress since being confirmed pregnant I know I shouldn't worry but I can't help but worry about the baby although I'm doing everything right.
