Sorry if this is a bit tmi...
Over the last few weeks I've had sex a few times using a condom as the only form of contraception (I only met my bf a month or so ago and everything moved a bit fast so I'm not on the pill). Nothing untoward happened, and the condom certainly didn't tear or slip off.
However, this morning I went to the toilet to find I had some brown discharge, and I've also been getting some period-type cramps, but my period isn't due for another eight days. As I've never had anything like this before and as I'm a hypochondriac, I googled it and 'early pregnancy implantation bleeding' came up. Is this something I need to be concerned about - it's another week until I can take a pregnancy test? Not sure I can wait that long? I can't exactly talk to my boyfriend about this as we're away from uni for Christmas and he's over 400 miles away. Does anybody have any experience of this?
