Stressing my self 😞

I know it's probably because of the losses I've had, 5 weeks, 5 weeks+ and a 20 weeks loss. So I'm on edge! I should be about 20dpo and I've been getting faint lines on curved ONLY. Well finally today I got a faint on clear blue. I got a got a negative on original first response this morning though. I'm scared that these lines aren't getting darker and it's gonna end bad once again. I've heard a few positive stories, if anyone has any more id love to hear them or your Input. I do plan on going back to my doctor the last time I went I got a negative test. Thanks lady's
