I missed a whole months period in may. Than in June it came on for a day n a half than back on at the end of June for normal time. Period has been normal. As of the 11th of this month I has sex and about a few days now I have tingling in my breast belly pains when I lay on it and a lot of throwing up my food. Test are negative. Period is suppose to come on the 29th. Did I test to soon?

Yes, you tested too soon.

Sorry, but it would be rare to have any signs in 15 days from sex. So no this is not a pregnancy sign.

You can not test till a week to 10 days after you miss your next period. So it is much too early to test
