Postponing TTC until I lose weight

Well my TTC journey has been 13 cycles (to date). I’ve seen plenty of stories on this app about women who have been devastated when their partner has literally ‘pulled out’ of TTC but it’s actually me who’s recently decided to bow out for the next few months while I lose weight.

I feel a bit nervous about the condom failing tbh and how ironic that would be to go back to using protection only to fall pregnant after attempting to TTC for the past 13 cycles. Also unsure (considering that we’ve had 13 failed cycles) wether it’s worth using protection.

Any thoughts?

Would a Dr advise me to stop losing weight while pregnant?
