Bfp two days ago, now cramping?? Please help!

Ashley
So I got my bfp at 14dpo, 2 days before my expected period. I had some very light brown discharge when I wiped that day too. It cleared up, I didn't notice anything yesterday at all. This morning(the day I was due to get my period) I have been experience AF like cramps. Not severe, but noticeable. So far, not spotting or light brown discharge but now I'm terrified. I also am still temping and I noticed my temp dropped from 97.90 to 97.72 this morning...any advice is appreciated 😥
