Uncertainty

I had a miscarriage in January. After that, we kept trying. Now, since Monday, I've been experiencing pregnancy symptoms: tender breasts, bloating, and some abdominal cramps. I think what I felt was implantation. I still have to wait 3 days for my period. I'm thinking about it all the time, and today I feel less bloated, which makes me really scared that it didn't work out again. Does anyone recognize this, and how do you get through until your period?
