So after an unexpected short cycle of 23 days I decided that this month I will be testing with opk everyday just in case I am missing ovulation. I started spotting on Thursday with full flow only really starting yesterday so I’ve classed that as CD1 and then today I got this result (see pic).. is it normal to get this so early on as it looks like it could turn positive within a few days... if anyone has experienced this I would really appreciate some advice.. or if it’s completely normal can you let me know 
Thank you!
