HCG levels

Found out I am pregnant on Thursday. Did a blood test that morning and results of hcg levels were 51. Did another one Saturday morning and got the results today and they had only gone up to 74. Just did another blood test and now have to wait until tomorrow for the results.

How do you not stress about these things? I’m already worried as it is with a bit of blood when wiping and cramp/period like pain.

This pregnancy thing is such a rollercoaster of emotions 🤦‍♀️
