Miscarriage March 25 ...positive test April 25th ?!!!!

Is it possible I got pregnant after miscarrying a month ago ,didn’t even have a period ..or can they be left over hormones ?!

BFP was there ,it appeared in less than 1 min

Help !

Update : it was confirmed today that I am in fact pregnant however it isn’t certain if it’s a new pregnancy’s or just leftover hormones !

Waiting for blood test Tuesday

Wish me luck ❤️
