I had a thought but took a test and it was negative

I had a thought but took a test and it was negative. I drank and had no idea I was one day late which is not normal for me.. So I took a test which led to four its showing that I am 2-3 weeks pregnant which means I'd e 3-4 weeks pregnant. I'm still shocked, I've tried and tried before and I am with someone who is not really ready yet.. But our baby is coming and honestly I am so excited nervous but excited it's been two years that I have been waiting for this blessing.
