Positive test this morning...now panic attack

Hello lovely ladie.s 💗 So all I want is a baby with my husband and I just got a positive test - which is amazing and what we all want - but now I feel so scared and anxious my heart is going to leap out of my chest!! Of course I'm going to buy more tests I only had one lol. We had MCs in 10/19 and 3/20. With my son in 2014 and with first MC my boobs hurt and I had morning sickness even before I had a positive test. The second MC I had no symptoms so I was devastated, but not shocked, when it turned out to be chemical preg only. I have no symptoms and I'm praying it won't be chemical again. HOW ON EARTH DO WE CONTROL THE ANXIETY? My hands are shaking and I feel like I need meds! Meanwhile we're still in shelter in place and my stepkids are running around here screaming.
