Ho @Pixie18 , so sorry to hear you are going through this. I had an ectopic in 2020, lost a tube too. I didn't even know I was pregnant (were ttc but hadnt missed a period) so a huge shock, didn't find out till it ruptured & was rushed to hospital.
I found it really useful to request a debrief with the hospital, they went through everything with me again, and I found it so so useful. I also had trauma counselling via the GP, it really helped.
I second @ElfDragon take a look at the ectopic pregnancy Trust, the forums are still there & are amazing support. There's also a load of supportive pages on Instagram, you'll find this sadly happens more than you think.
Re going forward, as you didn't have the injection you'll be ok to start ttc again as soon as you are ready, but I wouldn't rush, physically I felt ok but mentally it took a good while to be ready.
Sadly,I've had no pregnancy since, but I have numerous other things going on so I'm not 100% the lack of tube has anything to do with that.
Sending you love, be kind to yourself & take care
