Hi, I am 14 days late, sore breasts and even developing a bump. However my blood test taken 1 week ago came back negative and my ultrasound came back as a 4cm cyst on my left ovary. I had all the period pain when it was due, and cramping for 2 weeks. The cramps have stopped, still no period. Doctor didn't seem to know much about the female reproductive system and possibly because he is a man. I always have had a swollen cervix, not the cervix itself but the area surrounding. I am at a loss, and feeling very worried. I'm 26 years old, and not on any contraception. I am always regular (32 day cycle) and did have intercourse the day before ovulation. My last period was Christmas Day and lasted for 4 days.
