Sorry for the photo

I'm a mom of 3 boys I still breastfeed my 1 year old. And I was wondering if this discharge is a sign I could be pregnant or could stress cause me to have this much. I normally dont have discharge like this unless I'm pregnant but I'm on birth control pills and no we do not use condoms. I'm nervous to test because my boyfriend said I better not be pregnant because we cant afford another child... Fyi he only has one child the other 2 are from a relationship before we got together... am I just that stressed that this is happening or what I'm lost....

Update, so I'm getting a test today I was hoping that I would be able to have an appointment this month but of course I cant get in till Nov 20th... but also fyi today I've had 2 brown mucus discharge and I'm not due for my monthly till nexts month but also when i wipe there is little pink blood spots so fingers crossed that i am bit if I'm not I'm ok i just want to make sure it's nothing bad..
