When should I take pregnancy test?

My husband and I had sex last night three times, all which he finished in me (fully).

I took a plan b this morning just because I had it. Though I wouldn’t mind getting pregnant so soon, I also wouldn’t mind not being pregnant. 😌 Hope that makes sense. #recentlymarried

Anyways, I was on my period last night (last day) & I just officially finished my period this morning.

When would be a good time to take a pregnancy test? I’d like to know how soon I can find out whether or not I am pregnant.
