So scared. Any advice!!

Hi ladies. I'm 9dpo and had a BFP today!! Yahoo!! But.... I'm terrified of having a chemical pregnancy. This is my first month TTC my second baby and I'm glad it happened so fast but I'm down right terrified. I had a chemical pregnancy the month before I got pregnant with my daughter but it didn't even have time to set in because my period started the same day I got my positive result. Can Tewssing about it cause me to miscarry???
