Testing after MC

Last November I had a chemical pregnancy after TTC for 13 months. After feeling as though my body had failed me I went through about 2 months of really bad depression. I stopped purposely trying to get myself together. Ovulation was nearly 10 days ago AF due in 5. However, since ovulation I’ve had really tender breast which isn’t a normal thing for me until 3 days before. They have been sore for very long and feel heavy ( I’m small chested 34B). I want to wait it out it’s still nerve wrecking. But how do you get over the fear of testing again after going through a MC???
