Late Period

Most of these post that I have seen are very joyful but right now I’m getting scared that I might be pregnant, I would love to have a baby, I’m just not ready for one right now. Today will be my third day of being late according to this app, and I’m scared because I had unprotected sex with my boyfriend DURING MY MOST FERTILE DAYS, I’m kinda panicking, and I’m really scared to use a pregnancy test. He did pull out but what’s scares me is that we kept going at it. I don’t know what to do, it’s to late for a plan b are there other choices, I don’t know. I know this is very irresponsible but I can’t think of right now I need answers 🥺
