Temperature?

Shay
Posted this yesterday but didn't get any responses and really need help. My temperature rose to around 98.5 for a few weeks, then a few days ago it dropped to 97.3 and then it's been raising since then to 97.5, 97.7 and now 98.1. Could it have been an implantation dip? I also spotted brown/pink blood on the morning of the lowest temp,  only when I wiped. Thanks.
