Any advice ?

Am

Question ladies I am about 4 and a half weeks pregnant my son is 9 months old we didn’t think it would happen this soon for us when we started trying again as we struggled with infertility to conceive our son so my question is how long would you wait to go to a doctor? I’m terrified and I shouldn’t be but I live in a state where you can get changed if you have a miscarriage even for unknown reasons so that’s what scares me and I’m debating how long I should wait to see a doctor?
