Test

Hi everyone. I'm Sandra, 31, and I have a 2-year-old son. My period started on June 12, '17. I know from last time that my ovulation was very close to my period. I'm already experiencing a lot of symptoms. Headaches, fuller/sore breasts, cramps in my stomach and back. Exactly the same symptoms as with my first pregnancy. Still, I want to take a test soon, but not too early because it might be false if you're not pregnant. But when should I test? My period started on June 12, so should I take the first test on July 12?
