Oh Christina, I am so sorry for your loss hun. It would have been such a shock to go through the ectopic pregnancy, and losing your follopian tube as well .
All I can offer you is a huge hug hun, I can imagine how very painful it all must be. Please just know, that with time, and when you are healed physically and emotionally, you still have a follopian tube if you choose to get pregnant again. I can imagine it's the last thing on your mind ATM, but with time you might be open to the idea once again.
I am also sorry that your family is not fully understanding about your loss, unfortunatelly, they don't understand as they probably haven't been through such loss themselves, and sometimes they will focus on the positives (such as you having 2 beautiful and healthy children) to make you feel better.
Look after yourself, Christina, and be kind to yourself. You have been through so much, you'll need your family and friends to get you through this painful experience.
Beata xx
