Could I be pregnant?

Lately I have been having unprotected sex (not a smart move I know). For the first time I have gotten some pink discharge it stopped the next day then continued lighter then turned red and was white the next day.

That started on the 9th of april. I’ve been bloated all month and my stomach has been having some mild cramping and discomfort. I have missed my period took two test and they came up negative twice.

Today my breast are swollen they do not hurt just a little when I touch them and I still have a bloated stomach.

I am also a diabetic, I know because of my medicine I can have irregular menstruation cycles but this never happed before.

Thank you in advance.
