Luteal phase help

Jessica

The last two months in a row I’ve started spotting at 8dpo. I thought I might be pregnant last month and wasn’t and eventually (after 4 days) my period kicked in. So this month I know better and am thinking it may indicate a problem with my luteal phase…I’ve had my progesterone checked a few times at CD21 and it’s always normal or above normal. My temps yesterday and today were also pretty high so don’t think it’s low progesterone…but then why am I spotting early?! (Wasn’t after baby dancing either). I’ve not been drinking, getting good sleep, moderate exercise, and eating pretty decent. I’m so confused!
