Okay so I had sex Jan 4th and 17th protected like always with pulling out method me and my bf have been using condoms with pulling out to assure we're safe and it's been working for us for that long but my periods like 6 days late but I've been super stressed with school so I know that's why it's late this has happened before and I've been having subtle cramps to make me think it's coming but just for reassurance I'm good right I'm not pregnant ?
