Now i havent had an ectopic (although 2 mc and 2 ercp/d&c's) but i do understand its a bit more invasive than what i have gone through. having said that, the actual healing process is a very individual thing and unless you start feeling anything untoward (you will know it if you saw/felt it) you should be fine in time. But, again...it all depends on your own body's healing process. Worst case scenario is 4-6 weeks but you could be lucky and feel almost back to normal way before that.
Main thing is to get some tlc, listen to your body, follow doctors orders and only do what you feel like (this is an excellent opportunity to get out of stuff you dont feel like doing...but i digress, lol)
tale care and follow your instincs...if you start to worry then a swift call to epau to get your fears abated is always an excellent idea!
You will get better soon, hun!
All the best, Omi xxx
