Totally Bummed

Big time temp dip today. I know it *could* be an implantation dip, but I'm still totally bummed. What are the odds that it really is an implantation dip? I didn't have one last time, which is not to say I wouldn't have one this time, but still. My therm did beep fairly quick this morning when usually it takes a while (it is the target one) for the 97.00 reading. I took it out and temped again right after and it gave me 95.57 after taking the normal amount of time. After that I staggered to the bathroom and peed while being very upset. I went back to bed for a little while and then got up a few hours later. At that point I peed again and POAS that time for no reason other than to completely torture myself. Obviously between the temp drop and not using FMU I got a BFN. Ugh. I've been crying all day on and off. I'm really disappointed. I guess I'll be paying to renew my subscription to FF since it expires in 3 days. Ugh.
