When this current cycle started I had 2 cups of red raspberry leaf tea to help with cramps the first 2 days of my period. I've done BBT and charting for 23 months now and usually have a 31-33 day cycle. This month however I ovulated 5 days early (thank goodness I started also using OPKs or I'd of missed it) which means I'm expecting AF on cd26. The only thing I've done differently was the tea but can't find any info on it effecting your cycle length. Any insight is much appreciated!
