Need help? Its still possible a BFP?

Based on BBT and OPK I ovulated on CD14. Important to mention that on CD13 i started spotting and light bleeding for 4 days. I BD on CD12 and CD18 that week.  Today on CD23 I started a light pink spotting when I wipe after peeing. Also from last week until know I have some cramps and like a vaginal burning or itching ocassionally.
Please give me sone opinions about this crazy cycle.
