Nervous and worried 😩

Hi ladies I can't sleep, and have been googling my symptoms and now it's made me worry even more, I had brown spotting (small amount) two weeks ago and a little bit more last week which lasted three days and then stopped, called my GP and she offered me a 6 week scan I am currently 4 weeks, and I'm so nervous 😩 I had a chemical in August but wasn't like this, the brown spotting has small very short stringy bits in, has anyone had this before? And even though I'm four weeks, my pregnancy tests even the first one has come back with a strong clear positive, I know I shouldn't of googled anything. Has anyone had this? Xxx
