Ladies. .help please.

Me and my partner were laying down yesterday and we were like making out then out of no where I started balling like crazy..I couldnt stop..I felt so sad..but nothing at all was wrong..we had an amazing perfect day before I turned into a bigg ball of tears..

Now I just feel super deppressed cause I dont know why I have this terrible urge to cry..

I don't know if I am pregnant cause im too nervous to take a test but my boyfriend has been(tmi sorry) cuming in me everytime we have sex..
