So I've been taking the Birth Control pill for a month and a week now I've took it exactly on time every single day. It is the first time I've took pills and they're called "speintec" but I have a few questions about it

1.) Can i get pregnant if my bf cums inside of me?

2.) Can Birth Control pills cause a strong headache to appear ?

3.) If I have sex next next weekend unprotected and he doesn't cum inside me will I still be at risk?

4.) Since this is my first time taking pills and having sex will it effect me in ways like pregnancy ?

5.) Why do people think that taking Birth Control is such a bad thing ?
