Advice needed

I am currently 4 weeks and i have no discharge. Google is no help, and neither is my Dr, because they will not see me until i am 6-8 weeks. Is it normal to not have any discharge while being this early? has anyone else experienced this? i have had a miscarriage a year prior to this pregnancy, and a year of infertility, so this baby is deeply desired, and im worried if im not, and that something may be wrong. Has anyone had advice in this situation from a Dr? I'd love to hear feedback, thank you. Sincerely, an extreme overthinker who is about to go crazy lol
