could I be further along?

back in April on the 19th 20th and 21st I took a pregnancy test each day and they were all positive. I had a light period from April 15th to the 17th then I spotted from the 17th till the 29th. I went to the doc on the 30th and all test were negative. I had a 3 day light period may 14th till the 16th and missed my period in June. went to the doc and the test was positive. I feel like I could be further along than 6 weeks. I haven't had my first ultrasound sound yet. just curious on some peoples opinion.
