Educate me, please. Difference between pink and blue dyes?

4 days of a skipped period according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app.

No symptoms at all. No cramps like I normally do, which is strange. I feel nothing at all.

Boyfriend and I did have sex without a condom. He did not cum in me. Just precum. That was around Dec. 14/15.

Which test should I take?

Do you think I’m pregnant?
