So worried to take another test

Ashley
I have a Drs app today because I had 3 faint positives and a positive digital at 9 dpo. I've read of many people worried because it's faint so they take another one to make sure the line is stronger but I'm terrified to do that. I'm terrified I'll take it and it'll say "not pregnant". I haven't missed my period yet so it's possible for me to still get my period but I'm just so worried so I'm not testing and just waiting until my Drs app today. Anybody else have this? Did you ever get past it? TIA
