Will it happen


I’m 45 and have been trying to fall pregnant for several months now but it doesn’t seem to be happening .: my dr told me it’s totally achievable for me but why isn’t it happening??? I’ve had really sore boobs since a week before my last period which has never happened before and I have slight shortness of breath/air hunger

I also feel really bloated too??? Should I do a test my periods due in 11 days ?
