I’m 13DPO today and AF due tomorrow. Late morning today I had about 3/4 noticeable dots of red blood when I wiped twice, then nothing after that. (I don’t usually have spotting day before AF) I put a pad on just in case but had nothing from this morning. Planning on testing tomorrow morning if AF doesn’t show up. Any one had anything similar? Could it be implantation at 13DPO?
