Pregnant finally

I'm not having any big symptoms but i was supposed to start on 13th, got crampy but no blood. Thought i was the contraceptive because never been pregnant. Finally took a test. Bfp!!! Didn't believe took another. Same. Still wasn't convinced because it was a discounted pregnancy test so went out and bought a good one and yup pregnant with only a little urine because i had to go to the bathroom so badly i could not pee straight on the stick. 31 years old finally pregnant. Now when is a good time to tell people. I want to be sure i don't miscarry.
