Anxious about this!

So, I was told to start my birth control patch the day I start my period, which was October 26- November 1, and then I started back up November 4- November 10. My period was expecting to start on December 10 coming up. But the patch was SUPER ITCHY so I took it off on November 3, I guess that's why my period was on fucked and started again on November 4. But I'm also shocked that I got pregnant that fast after stopping birth control 🤣 Just took one time, again.

But I have noooo idea when my due date is, because of the weird period and with being on birth control for a little.. All I know is, I didn't get a positive until this week so I know I conceived on November 21 but we will see on ultrasound in a couple weeks when I'm due I guess 👀
