Hello ladies!

I’m late on my period and this happens sometimes because I had the marina for years and ever since I took it out Emi period have. Wen irregular, but never 14 days late. My fiancé and I have had sex and he did put his baby juice in me... but that was already when I was 5 days late and the last time we had sex before that was 3-5 months before. What should I do? I’m going to get a test ni matter what. I’m just confused not scared because me and him want a baby, I have a 9 year old and he has no baby’s. So if I am I’m going to be sooooo happy!!
