Hi, can someone please explain the whole birth control process.

I'm extremely lost, I first got on tri lo sprintec for acne purposes and it has done a great job so far but I don't know anything else.

For example, does the pill remove any ovulation/fertilization period?

How good does this pull work if let's say my boyfriend/husband were to cum inside me?

I've been told The Pill slows down your metabolism and you begin to gain weight?

I've also been told my boobs will start growing?

Also lately whenever I've been getting horny I don't get wet? Like it doesn't matter if I'm the most turned on ever, there won't be any lubrication. That's weird for me? Is it due to the Pill?

I've also gotten my period twice in one month

Can someone please tell me their experience or their knowledge with great detail please. I'm completely ignorant to everything within this topic.

Thank youuu!
