What would you do?

We've been ttc #3 for 5 months now, so i went to the gp for a general check up. My bloods came back with low iron and vit d so now I'm on supplements. But I also came back with slightly elevated amylase and lipase. Scan of the pancreas shows no inflammation and all other results were normal. They've referred me to a specialist and asked us to hold off on ttc while they investigate as they're stumped. I did ask what would happen if I fell pregnant and she said nothing as my levels are only slightly high, they just wouldn't be able to investigate the cause properly. I have severe endometriosis and each month I see our chances decreasing as I know it is getting worse. Would you wait or keep trying based on the dr saying everything would be fine?
