I had unprotected sex 3 days before my period and it came out different can i be pregnant?

I really need to know the chances of me being pregnant or not .. im only 18 ..yes i want a baby but i dont want to worry anyone if im not ...

I'am pretty sure that you are pregnant...But to have no worries you should take a home pregnancy test they are 99.9% accurate...

I took a home pregnancy test it came out negative. is it to soon to take it because they want me to take a blood test will it come out for sure there

The same thing happened to me. I had unprotected sex with my fiance on Fri, 2/19 and was scheduled to have my period on Mon, 2/22. As expected, I had my period, but it was extremely lighter than usual. My periods usually last 7 full days with 2-3 of those days being heavy. (Note: no birth control in the picture.) This time (3 days after having sex), my period lasted 3 days. Maybe one heavy day, but it still wasn't even considered heavy for me, at all. I can't even stand having to wait an entire month to see if I get another period. Should I have any concerns at all? I'm impatient when it comes to the waiting game. My fiance is deploying shortly...pregnant or not pregnant, we'll be happy with the result, but we both wouldn't mind having a little one running around. Would you say this was an abnormal period or possible symptoms of some sort?
