I take Yasmin too and often get an unexpected bleed. If you keep taking the pills you'll get this spotting possibly up until the next break, so you'll have an extended bleed. If this puts you off, you can stop taking them now to let the bleed come, then restart in seven days time You could even finish the current packet, have the next packet then have a bleed. The tablets in a packet of Yasmin are all the same so there's no phasing to worry about.
