What would the chance of pregnancy be if I had unprotected sex during my fertile window and then 2 weeks later I got my period. And now I’m due for my next period but it’s late and I’m having early pregnancy symptoms. Keeping in mind I haven’t had sex between the time I mentioned and now.

I went to go visit my boyfriend who’s in the military back in mid March. Stayed on the base for 10 days. We had unprotected sex during my fertile window, hoping to possibly conceive. Ended up getting my period on the second of April about 2 weeks after the last time I had sex. My cycle is usually 21-25 days long so I’ve been expecting to get my period between the 22nd and 26th of this month. It is now the 28th and I’m late AND experiencing early pregnancy symptoms like breast tenderness and morning sickness. I know it’s not likely, but what are the chances that I could possibly be pregnant? Has anyone else gone through something similar to this?
