So last Friday and Saturday my boyfriend and I had intercourse unprotectedly, however I am on the pill and every time he pulled out and there was no ejaculation within me.
My boobs have hurt for the last week and a couple days and on Monday I was sick and had a fever of 101. I shod be expecting my period soon but I think I'm just over thinking this right? I don't have any symptoms of a period or pregnancy other than a killer headache and my tender boobs, but they feel fine now.
So... I should be fine right?

No birth control is 100% effective. Pregnancy is possible.

Here's the thing, it's been less than a week since you had sex. You wouldn't have pregnancy symptoms yet. You also haven't missed a period, which is the first symptom of pregnancy.

Sounds like you're coming down with something.
