Help please

Patient: Hi, the start of my last period was February 23rd and it’s march 28th now and I still have no period. So I’m at cycle day 34.. I’m not sure what is normal for me, but I don’t think I’ve ever had to wait this long for a period, and I was told that the normal cycle day is between 22 to 28 days. I took a pregnancy test a week ago but it was negative. When should I take another test? Do you think it’s a good possibility that I’m pregnant?

Symptoms: Breasts are sore, tired ,

Doctor:
