Is this normal?

For those who don't like details about someone else's cycle please stop reading now. Ok, so this morning I had a small bleed.  I had no spotting overnight but stood up in the morning and had the sensation of bleeding that was quite quick. The bleed was bright red and probably about 15-20ml. It stopped immediately and I had a small amount of brown spotting during the day. Sigh. Why is this happening??? I'm not due for my period for another 9 days. The brown spotting happens every month and and the short red bleeds have occurred every few months. Is there something I should be doing? My acupuncturist did hint that my progesterone levels could be low and adjusted my herbal tea accordingly when I saw her last month. I try and ignore the spotting and just get on with my day but it is a constant reminder for nearly 2 weeks of the month that things maybe aren't quite right. It's been a bit stressful at home because my husband no longer has permanent work and I'm having to increase my workload to bring in a bit more money. It's a wet day outside and I feel like a nice warm bath but our hot water service has broken so it'll just have to be TV in some warm trackies (tracksuits). I feel a bit down after this post so I thought I'd finish with 10 things that make me happy to cheer me up a bit. They are: 1) my husband 2) my family 3) my friends 4) weekends 5) chocolate 6) my subscription magazine 7) my favourite TV shows 8) playing sport and exercising 9) the view outside our window 10) spending time in the garden. There, I'm smiling already :-)
