Implantation Dip?

Hi Abba. Please let this be it! Let us be pregnant! I'm really wondering if I am pregnant as I've heard of this happening to people. My temps have been very high after ovulation and have continued to rise, 10dpo they dropped significantly and I thought AF must be on her way. Took my temp yesterday morning and they're even higher than they were before at 98.9. I know some people have told me that they've had a significant temp drop when implantation occurred, so now I'm really wondering. The thought puts a very big smile on my face, but I guess we'll see in a few days. I'm going to get a bloodtest on Wednesday if AF hasn't shown by then to find out for sure.
