Opening the pool on a rainy day

So were opening the pool today and it turned out good this morning, draining and setup. Now I'm waiting on my dad and great aunt to come home with the chemicals needed and fliters. I'm so excited we never had a pool before between the two of us and if this rain stops we can get the rest of the pool done and ready for cleaner water. It should be ready by saturday if it works for us and warm enough to swim. I want to at least try to swim 1 time before baby #2 comes and then I'm laid up due to my c section. I know everyone of my family and friends will enjoy it!
