2ww question...

Has anyone during the 2ww started spotting that lead to mild bleeding dark brownish red mixed with (mucus) not soaking a pad at all, just enough to change mabe twice (TMI) almost 5 days before your period was due, feeling nauseous with dull cramps to the right side?..

also my Bbt is usually 97.7 or 97.6 its is now resting at 98.1 the last 2days 💁 i had O on Sept 8th or couple days before..

dont know if im out this month or its just mild implantation bleeding😟TTC
