Hi, I wonder what people think might be going on with me! cos I don't have a clue 
We have been TTC for about 5 months and my cycles are normally v regular (28d), but this month I started spotting about 7 days before AF was due.. TMI.. DH and I were SWI and it was after this that it started. It was brownish at first, but then went more reddish over the days. At first I was excited, thinking it may be implantation... but now 5 days have passed I am still spotting :( I do usually spot before AF, but only 2-3 days before, so this is really unusual for me, and a bit worrying.
do you think this is worthy of a Drs appointment, or does this sometimes 'just happen' ?
I guess until AF shows/no shows I don't really know what is going on, so thought I would see if anyone else sometimes experiences this.
