How fast did your BFP line show?

Hello!

I'm trying to gauge if this pregnancy could possibly be twins again.

First pregnancy, I was about 4 weeks and the positive line showed up so fast I was in shock! Found out at dating scan it was twinnies! The second pregnancy (mc) the positive line took about 2 mins to show and I was about 3/4 weeks. I lost that one two weeks later.

This pregnancy I tested at 4weeks 3days from LMP. That line showed up so fast again! I won't be seeing the doctor for another couple of weeks so I am wondering if any of you also had lightning fast lines, and only one bub. Please. Give me some hope haha.
