Could I be pregnant?

So my husband and I had intercourse on the 15th and the19th 20th 21st 23rd 24th and the 25th and 26th. On the 15th and the  19th 20th 21st and the we used the pull out method and on the 26.  On the other days he came inside me. I want to be pregnant after going through a chemical pregnancy last month. I waited until after my first cycle but I would really love a baby my husband wants to start on September 28 but I am ready now. Does anyone think there's any chance that I could be pregnant?
