Worried!! But excited!

Katrina • Pregnant! Due Sept. 12th
Well I took a pregnancy test yesterday and it was positive. I just had a MC 3 months ago and I'm hoping this time it sticks. I was 16dpo and 4 days late on AF. I'm worried and nervous. I'm cramping a little today and yesterday but with no blood and I'm discharging. Does this sound normal? Or signs of another MC. Just really hoping this sticks
