I Am In My 12 Weeks Pregnancy Now, My LMP

I am in my 12 weeks pregnancy now, My LMP is June 20th 2015. I had duphaston tablet for 20 days from LMP. Dr. informed me everything fine as per my Ultrasound scanning, blood & Urine test reports.
I migrated to some other place and consulted another doctor today but he prescribed Duphaston again for me for 60 days.
I got pregnancy this time by taking the Medicine Clomid( daily two tablets in morning) I didn't experience any spotting till today during this pregnancy but i have two BOH: 1. Abortion in 6 weeks- Feb 4th 2013 & 2. Ectopic pregnancy in May 2014 and done partial salpingectomy for my left fellopean tube due to rupture. Have any problem to continue with Duphaston
