Scared to test ☹️

DH and I have been trying to conceive for 2 years now. I was on Depo from Jan '13- Nov '15. It really messed my up. My period were all over the place sometimes coming on CD 57. I could never tell when I would come on my period. Never had symptoms except sometimes feeling really sick. This is my first round of clomid and everything is different I had cramping immediately after ovulation and other symptoms. I cannot tell if clomid is resetting my body or if I could be pregnant.
