Is it strange to be afraid to take a pregnancy test?

Not at all: You could be dissappointed if the test result is negative. Or you could be upset if positive. Becoming pregnant is a life changing event - some apprehension is understandable.

No: What I CAN tell you is that avoiding something just because you are afraid (avoidant coping) is, even in the short term, a life-ruiner. To be brave, act brave. You may be surprised that you anxiety disappears when you actually begin the process -- as a first-time skydiver's fear vanishes on exiting the aircraft. I hope you get the result you want.
