I’m so confused

Teresa

I’m having a really hard time this month. I usually have the same PMS symptoms about 6-7 days before AF followed by one light day of period then full throttle. This month; however, NO PMS symptoms at all and my period was three days late.. I’m never late! I had very light spotting for two days (barely anything when id wipe) now there is more blood when i wipe that appears to be AF but NOTHING on pantie liners... I’m still without usual symptoms... is this normal when you are ttc? I haven’t had a shift in cycle since I was a teenager...
