Is it too soon to tell?

Hi everyone.

So I stopped taking my birth control because it was causing unbearable mood swings. Anyways, my boyfriend and I had unprotected sex last week. This week I’m feeling so tired, like it seems like no matter how much sleep I get I feel exhausted. Also, my boobs really hurt. While I was on the pill and even before they never hurt like this. I can’t even wear a bra because they’re so angry.

I’m just wondering, is it too soon to take a pregnancy test? My period is due in 13 days Should I wait to see if I miss it?

Please help. And thank you in advance!
