More and more anxious

My anxiety during this pregnancy is so hard. I worry about everything and wait for the scans to at least put me at ease the smallest bit but they always seem so far away. Had another appointment with my midwife to discuss blood work and it turns out I’m A negative which means I basically have to be extra cautious about bumping the bump and I could not be more paranoid about the slightest nudge on my bump. No wonder my blood pressure is high haha I can’t wait for my 20 week scan in 3 weeks time to calm some anxiety

Any tips for keeping your cool and not over worrying for the rest of my pregnancy ?
