Period questions ....

Ashley

Period was due on Thursday (July 13). I have had extremely light spotting for the past two days. Today I had maybe half a dime size of brown blood on my pad. When I wipe its completely clear. My periods are usually pretty heavy. If I reach into my cervix, I have a small amount of blood on my finger. My cervix is extremely high and my temps are staying the same or rising. My temperature this morning was 98.1 and normally during my period temp is around 95/96. I took tests on 13dpo and 15dpo and both were BFN. Haven't tested since then. On Wednesday I had yellow thick snot like miscues, Thursday and Friday was creamier and today its watery ew like. Any ideas?
