Hi, I’m really sorry this has happened to you. I had my ectopic at 6 weeks and was told the injection was my only option as it wasn’t big enough to need surgery. If they have given you a choice I would say injection. I had an injection, it’s very painful and I had to lie down to have it (the doctor initially was going to give it to me standing! I would’ve fallen)
There are side effects to consider and am sure is not the same for everyone. For me I had severe stomach pain for a week and still after a month get a twinge every now and again. You can’t get pregnant for 3 months after the injection because it stops new growth which would kill off or seriously damage a new pregnancy but they said after 3 months it would be perfectly fine. But now I’m terrified I might get pregnant by accident despite using protection, even though it took us 2 years to get pregnant in the first place.
Anyway sorry to go off on a tangent. I’m surprised they gave you an option and I would suggest that if the doctor’s think the injection will be fine then go with that. But I also read that even if you lose a tube, your ovaries can use either tube so you would still be using the eggs from your left side. Check with the doctor about that. Also make sure he knows about your history! He should know.
I hope whatever you choose turns out for the best.
