Ok so I know that the chance exists that I could be pregnant because I was stupid and didn't use birth control, actually I was stupid twice. My question is, this happened 5 or 7 days (sometimes my cycle is 26 days and sometimes it's 28) before my next period. If i'm pregnant will I miss this period or was it too close to my next period for me to miss it? Might be a stupid question but i'm really unsure and I don't want to go assuming that i'm not pregnant if I get my period. I know I should just take a test the day i'm supposed to start my period but again is it too soon after possible conception? I did take a pregnancy test today and it was negative but i'm sure it was probably too soon.

Also a few days before that we did use a condom but the condom came off, but he also didn't come. Is there a chance of getting pregnant because of this as well?
