sorry you've been through this x
I think it was a bit insensitive of your dr to word it that way, were there any particular circumstances that indicate it necessary to wait longer than the shortest time to ttc again?
i think different drs have different ideas of how to progress, i think you should concentrate on your loss and feeling that until you can see them again, and if you havent made the appointment, get it booked in so you then get to hear their side asap and you know what you are dealing with
theres lots of theories about waiting to try - from what i can gather, none of them are fool proof or universally agreed upon unless there are specific circumstances - and you have to do whats right for you. There does seem to be agreement on making your future ttc easier by waiting for af for dating purposes, and to make sure you are emotionally strong enough (bit bloody rich seeing as what takes us forwards is trying again in the first place)
ask your dr why they feel it appropriate to discuss contraception - find out what they think its right for you, and then you can react in the most positive way. For eg, do they think your risk of mc is increased if you dont wait? If so, why? Some drs think that the lining of your uterus needs to get thicker - then others say the egg wont implant if its not thick enough so thats less relevant to waiting for eg
hope you get some answers
