CM question

Lisa
Ok so I am CD 29 and my BBT chart has been all over the place. Yesterday and today I have had heavy EWCM with very light blood streaks in it. Any one have any ideas what it's from? It's not normal spotting light pink, it's like literal streaks of blood in the CM. sorry for TMI lol but I need help haha. Thanks! Oh also because of my stupid PCOS cycles we BD every other day so hopefully this is a good thing?
