How many weeks am I? I’m going mad!!

Hey everyone, I’m driving myself crazy at how many weeks I am pregnant because I’m too inpatient for my midwife!!! So my last period was 6th jan, lasted 5 days. Pretty irregular periods varying from 30 days to 45. I ovulated 28th jan but done the deed 23rd 25th and 26th jan. I done some clear blue tests , one said 1-2 weeks and two said 2-3. My lines are pretty strong. I was in hospital last week and had to have an ultrasound for other reasons and they took pregnancy tests that came back negative (before I knew I was pregnant) but all this was ONLY a week after I ovulated and obviously conceived. How many weeks will I be?!?!
