What's my deal?!

Jovanni

So I have been ttc for 3 months now, 9 months ago I had a miscarriage (empty sac) and ended up having a d&c. Everything went by the books and my periods went back to my normal 28-29 day cycle. I am two days kate, sore breasts, fatigue. I took a test and it turned up negative. But I feel like something is up since my breasts never feel this way and my periods are usually on time. Any ideas or advice ?? Trying not to get my hopes up.
