TMI. First time using digital Ovulation kit. Husband and I BD from the time it read "high" to 2 days after peak. I later had increased appetite, sore boobs (though not bad), nausea (no vomiting) and lower back pain. Today is when I was supposed to start my period. I've always been regular, down to the day, and never been on birth  control. My flow is always super heavy and super predictable. A few days ago my cm had a slight yellow tint. Yesterday I saw a pink tint as small as my pinky nail. Today, no period and then I wipe and have bright red blood, so I'm thinking its AF. I put on a pad and 6 hours later, there's no flow. Tonight I wipe and clear, and if I do a CM check, there's very small amounts of dark brown mixed with creamy CM. I'm really confused. I have no pressure down there like I normally do around this time, and don't really feel it coming on either. Tomorrow I am going to take a test- I'm sure AF will appear, but does anyone have an educated guess or has this happened to them? Please only respond if you have a valid experience or valid info. to share. I don't want to be confused further! Thank you in advance!
