I FEEL PREGNANT?

Ella
Never really had proper sex, the only 'sex' I've had was back in November and it was the tip jus beginiing to enter but it hurt so he pulled out after 3secs. I've taken 6 pregnancy tests which came out negative and I've been getting regular periods with PMS. I've counted and if I was pregnant I'd be 19 weeks. I just feel like I AM pregnant, u know guys? 
Anyways 
Plz go easy on me in the comments, don't call me stupid or whatever 
Thanks :)
