Sorry for your loss
I had an ectopic pregnancy just over 4 years ago. I had emergency surgery to remove my ruptured right tube (they had to cut me open, so I didn't have the keyhole surgery). I was advised to wait 6 months before trying again, but only waited 4. 11 months after my Ectopic I was pregnant with my DS. I have also then gone onto have a further 2 pregnancies (DD2 took 14mo to conceive, this pregnancy was about 10mo of unprotected sex, & leaving it up to "fate").
Good luck, hope you are on the road to recovery and have a quick TTC journey!
