Dear Specialist, I Have A Few Questions. I Had A

Dear specialist,
I have a few questions. I had a 8 years relationship with my boyfriend. In that time I have had sex with my boyfriend uncountable number of times. I also became pregnant 2 times in those years. Last time in July 2015. I took pil ( Isovet)l to abortion. I take 1 pill orally at night. And push 2 pills into my vejaina. At 3/ 4 am bleeding was started. I didn’t do anything else except having pill.
Now my questions are:
I am getting married to another guy next year. I belong to a conservative society and I am marrying a guy from a conservative family, as arranged by my family. I am worried about the consequences it might have for me in the future.
Is there any possibility to find out my previous pregnancy? Is there any common test through which it can determine? if I m planning to be pregnant with my future hubby, should I face any problem because of the pill I took for abortion. If the answer is yes what should I do now? How can I hide my previous pregnancy incident? I don’t want to face any problem before and during my pregnancy period.
Plz let me know the pros and corn that may be I have to face…
