Weird Period

Okay ladies please bear with me🙈 my period was due on the 17th of this month, here is how it went:

10/17: dry clumpy brown light discharge

10/18: dry clumpy brown light discharge

10/19: very dark red bleeding in the morning with few clots, then brown light bleeding

10/20: brown light bleeding

10/21: light brown sticky discharge in the morning, egg white discharge in the afternoon, dry clumpy white discharge in the evening.

My question is; was this a short light period?? My period is usually medium flow and 7 days long. This was a light flow and for only 5 days.

I want to start TTC this month and need to calculate my CD. Should I consider 10/17 CD1 (with only dry brown discharge)?

Any help is much appreciated!❤️

Thank you ladies
