Feeling regret

So I'm on cycle day 38. Never had a late period in my life except with my first two pregnancies. Anyways I've been getting bfns so today when my hubby asked if I wanted to get on the four wheeler and ride I did and had the most fun I've had in a while. Well now here I am over analyzing it. "What if I am pregnant" "what if i hurt my baby and didn't know it" ughhh shoulda just stayed home. 😕😓😣
