Am I pregnant?

My last period started on December 25th. I had this on January 23rd. This happened about 3 times that day and that was it, the next day I wiped once and had red, mixed with mostly a mucousy film that was clear. That was all I had. I was supposed to start 2-5 days a go according to the eve and glow apps. I have taken 2 EPT's at random times of the evening and both were negative. I took one first response this morning and that too came back negative. The past couple of weeks I have also had migraines that have been so bad they make me nauseous, light blood and that was it. I was also supposed to start taking BC the Sunday after the 25th but didn't until like a week later, took about 2 of the pills and that was it.
