10DPO - Big Fat Maybe?

So today I am 10DPO and I am pretty sure I am pregnant. I did test earlier and got a BFN but it's still early and I think it was a rather dilute sample.  I'll try again in the next few days.

Symptoms wise I have sore breasts and particularly unusually sore nipples, light cramping in my lower abdomen, high BBT (and my evening temp is around 37.5 which is over a degree higher than my normal evening temps - this was a symptom during my early pregnancy with Lily).  I am also very tired though not sleeping great and have a rather unsettled stomach.  

I'm excited that this could be a BFP but also very scared.  I'm not sure how I would be able to handle another loss.  I am hopeful but trying not to get my hopes up too high
