Ectopic pregnancy

Hello there! I found out i was pregnant a week ago, unfortunately a few days later i started having cramps and spotted. Went to the doctors, they only found a water bag in my womb. HCG levels was at 69, 48 hours later my HCG levels went up only 6%. Was sent to the radiologist to scan and was told that i have ectopic pregnancy and need to stop my pregnancy. Has anyone went through this before? What are the chances of having an ectopic pregnancy again in the future.
