Pregnancy symptoms?

I missed my entire Match period and have been sexually active. I turned 21 in March so my boyfriend made me take a pregnancy test just to make sure it is safe for me to drink.

I took the test one week after my period was exactly one week late (according to my menstrual calendar, but it’s never accurate). Test said not pregnant. So I drank that weekend and the following week (not an outraged crazy amount).

I missed my whole period and April 1st my undies had a dark red discharge but when I peed no blood came out. Yesterday I peed a lot because I had drank a lot of water and coffee and my pee was regular until about 5pm

Where a bit more blood came out. Later that night I felt discharge come out so I went to the restroom and it was blood like period blood. I slept w a pad on and barely any blood was on it. I used the restroom in the morning and it seemed like regular period blood? Should I be concerned or could it just be my period
