Stress or not stress?

So around Christmas up to like i believe jan 1st or so ive been intimate with my bf and im two days late but my bf put me under so much stress sincewe live with my adopted family and my bf and i had a very tough time so im not sure if im just so stressed out that im just late on my period or not .. Im kinda overwhelmed my adopted mom told me rn isnt good for me tto have another baby so its kinda not a good thing to ask her to get a test and my bf on the other has been looking for work til he goes for his medical screening for the national guard since hes going back to the national guard ...im not sure what to do im getting chest pains as i type this so idk
