how do I stop being so paranoid ?!

So I'm about 5 weeks pregnant!! Well I got two positive pregnancy tests Friday night! & I keep watching & reading things about ectopic pregnancies & chemical pregnancies & how some women had positive pregnancy tests at home but when they got to the hospital, they were negative for being pregnant! Y'all I'm scurred lol! Please give me some advice! Plan to go for a blood draw tomorrow Lord willin!
