Need advice

Kelli • Baby #1! I can`t wait to have our first little one ❤️️❤️️
I am about 4 days before my period and usually by now I have some symptoms like a sore back. And I am not experiencing any of them. I had a short period last month (2days instead of 6) I've been to the dr they said no to pregnancy but do you think it's possible?
