Some please tell me if the chances of pregnancy are high or not (symptoms listed below)

I am on day 55 of my cycle. On day 46 I had light green cm and I have no infection and I read that it was a symptom. All my tests are negative. I’ve had a little cramping a few days ago but nothing like my periods. I’ve been moody, and bloated. Noticed my abdomen was a little harder than normal along with my breasts. Boyfriend said they look bigger and feel different but I’m not 100% sure. I’ve been eating things that you couldn’t even get me to smell, now I love them. Some days I’ll have severe hot flashes and headaches. Yesterday I had a headache that also made me nauseous like I usually get when I’m carsick. My periods are never really regular but I don’t think 55 days is normal either. Went to the doctor asked for a blood test and they wouldn’t do one unless I’ve been trying for over a year. I’m hella confused. I took a test this morning and again it was negative.
