3 Corpus Luteum at 5 week scan - Triplets??

[briggsy's girl]

As I said earlier, your ovaries aren't smart enough to recognise how many embryos implanted. The hcg doesn't just hit one cl and close the rest down. They all have the the exact same response to the hcg so none of them will disappear until the placenta takes over

You'd get the exact same response if you continued luteal phase support shots with The trigger drug (puregon or similar) as they have hcg in them so the cl will all respond. It's a good thing. Should give better support to your pregnancy than a single cl.
