Anxiety help

I honestly fear so much with every feeling like the pulling/ tugging or small cramps feeling... or everytime I use the restroom I fear to see blood. Did any of y’all have anxiety in other pregnancies or have them in your first? I had a miscarriage before at 6 weeks but I am now 15 weeks so I’m feeling kinda okay.. are these small cramps normal though? Please help with any advice .. also sometimes I feel like this app makes stress 10X worse
