I took a test ten days after it was negative. I really want a child

I stop my pill when it ame to the green ones then two weeks later me and my boyfriend had sex. Then a week or less later I started feeling cramping and it stayed that way for a week. My breast are tender but not so tender I just had sex two weeks ago. I'm ot feeling the urge to throw up. But not actually throwing up. He finished in me btw. I took a test ten days after it was negative. I really want a child :/
