You can.  No problem in that.

am I allowed to fast every Monday and Thursday for the rest of Sha’baan? I started on the 12th which was a Thursday then also fasted Friday, Saturday and Sunday as they were the 3 white days. I made an intention to continue fasting every Monday/Thursday and every white day for as long as possible Insha’Allah, so would be allowed to carry on or not?
