Hi. Me and my boyfriend wanted to try putting only the tip in and that’s what we decided to do on Friday, August 14th. We used a condom at first but then he took it off, and he did not precum inside of me. I decided to get a pregnancy test that same day just in cause and Saturday I started cramping. I’m still cramping with I believe light bleeding. I only bleed when using the bathroom and I made sure I got a Plan B pill Sunday. Should I be worried?
