Thank you for posting your question here, I will try to answer it to the best of my abilities.
Yes, you can try for pregnancy
and I suggest you try and have unprotected sex on the days when you are ovulating, this will greatly increase the chances of you getting pregnant.
To calculate the days you are ovulating, add 14 days from the date of your last period. The 4 days after that are the days when you ovulate.
I hope this answered your question.
