Pregnancy question

[IzaBella5]

Hi, I've finished my last pack of pills last thursday. Had bleeding from Friday to Monday then Tuesday started a new pack, took pill Tues and Wed then forgot and took again Mon Tues. Problem is on Monday morning I started bleeding bright red blood and is still going. Did a pregnancy test and was negative. I have some cramps and conatipation too but I don't want to think of them as additional symptoms. Could I still be pregnant? Hope someone can give an opinion. Thanks
