BFP! Twins?

Bria • 30 years old - Married - 20 month old

I’m 12 Dpo and i got my BFP today! I have had 3 miscarriages one being in august so I’m hoping for a sticky baby.

Compared to my last pregnancy the lines are so much darker. Could this be twins or do the lines look normal for 11 and 12 dpo. Period is due tomorrow.
