Is it too early?? Pregnant or just plan b ??

So 17 days ago me and my husband had sex and the condom broke,

I took plan b after an hour ( I was ovulating around the time we had sex either the day before or the day of I just know It was my fertile window day)

But. when we found out about the condom, so 7 days after taking plan b

I had a bright orange like spotting for a day and four days after the bright orange spotting it was brown and light red (pinkish like) the spotting came 7 days before my period was due.

And I am now 4 days late on the period I am supposed to get, I don’t know if plan b made my period came early or not but I want to know if it is too early to take a pregnancy test ?

We at first didn’t wanna have a baby right now but if the pill didn’t work we will be happy with the baby
