Worried and ttc

Holly • I am 25 I am married to my high school sweetheart. I am trying to conceive after an ectopic pregnancy in June 2014.
June 5 I was pregnant but then found out it was in my tube so they had to take my right tube out cause there was no saving it I am really wanting a baby I am 24 and want a baby before my 4 year old gets to much older we have been trying for 4 month now but I am sooo nervous because what if I have a tubal pregnancy again and loose my left tube then I won't be able to have babies at all anymore and it scares me does anyone have any tips or advise to make me feel better. I would appreciate any feed back!
