Really need someone else's opinion please! Implantation?? Or something else??

MrsCriss
So my Dr thought I had a chemical pregnancy a few weeks ago I only bled heavy for a few days then it quite so we started ttcing again the day after my bleeding stopped I didn't start taking opk tests until about cd11 like I normally do and I have not got a positive one yet and never do so I'm thinking maybe I ovulate early.. I have been checking my Temps and cm as well and the few days after my period I always get ewcm and then never really much the rest of the cycle well my bbt has been in the higher 97s to 98 but then on the 29th it dropped all of a sudden down to 95 degrees and then went back up to 97 again the next day and I also started spotting and have been spotting ever since and my temp is still in the 97s could it be implantation? Or something else? I've also had some light pms symptoms and some other strange sypmtoms and been so tired it's not funny.. i would have had to ovulate only a few days after I stopped bleeding in order for it to be implantation but is that even possible??
