Passed my AF, worried because PT was negative.

I'm way past my expected period. still negative on the pregnancy test. negative for ovulation test. I had the IUD taken out last year in November. my period has not regulated. I'm more than worried my period will come any day and I'm feeling stressed. my last period lasted for three days max on January 29th. I do want to have another baby. my first one is amazing. any thoughts? encouragement? feeling a little stressed and uneasy, maybe go to the doctors?
