Anyone else get pregnant before first af?

I just went through a natural mc from dec4-8 bleeding stopped the 8th and had my blood drawn and my levels were at a 6 almost back to zero. Around dec 15th-17th I had a lot of ewcm and symptoms of ovulation. Yesterday I started feeling a little nauseous and today just extremely tired a lot of same symptoms I felt prior. I'm still awaiting my period following the mc but wondering how likely the chances of getting bfp, and how soon to test? Anyone else have any success stories?
