Pretty sure I'm going to miscarry. Just waiting. πŸ’”

I know I shouldn't, but I've been testing frequently. This is my second pregnancy and I am presumably 5w 2d I've never had a miscarriage, but I was for some reason, irrationally anxious about it this time around. It sort of consumed me and I e felt negative from the start. I was testing frequently and my lines were never super dark but they did darken... Aaaand then quickly lightened. My positive lines are now almost non-existent. The one I took today was a faint squinter and hours later has now disappeared from the test.... I noticed the severe drop about 3 days ago but I still have yet to cramp, spot or bleed. How long will this take? I just want to move on. Also, why am I still having pregnancy symptoms that seem to have progressed? 😞
