Pregnant after taking plan b

Rational

I took Plan B within the allocated 3day timeframe (however I ovulated before taking the pill ) and i am pregnant pregnant . My cycle isn’t due to come down until 4days however I’ve been feeling nauseous and decided to take one early and it surprisingly came back positive.

Disclaimer: I decided to take a plan B because the month before I had a chemical miscarriage and my emotions were extremely all over the place and I just didn’t know if I was ready to give it another try right now however God had other plans and now I’m just living in the now trying to be calm and cool with the situation
