KKH generally do not test progesterone when we do BHCG BT. But some private clinics do as they are more kiasu and want to give adequate supports esp if tested positive. So if you want to know, have to request it from the nurses when doing BHCG BT. After 5 years of IVF and 2 miscarriages, i have become more kiasu so i always do progesterone BT when i do BHCG BT.
For those who bleed earlier than should, its a sign of luteal phase defect so it might be good to get tested while you do your BHCG BT. Anyway its drawing from the same blood. But of course, if you are comfortable not knowing then its your call. I just tend to be more concious and kiasu given my history and that ivf pregnancies are so so precious.
I know some people feel if our body cannot naturally produce enough progesterone to support the pregnancy means the embryo may be non viable to begin with (thats why the low progesterone). And that in this case increasing supports also no use cos we might just be saving a non viable embryo.
But thats not always the case. In fact, like what Dr Zou tells me, sometimes it can really be our body are generally too cold or we have other conditions hindering progesterone and thus not being able to produce enough progesterone even when we can be producing perfectly healthy viable embryos. In such cases, the embryo just need a little push start help. If given the little bit more help, the embryo can go on to become healthy baby.
So it might pay to always fight for more supports in the early stages and see how the pregnancy progresses. Until at least week 6-8 where we can check for sac, yolk sac, fetal pole and heartbeats, we should not give up on our babies. Furthermore, some baby are late bloomer, initial scan may even be discouraging but given another week or so, you be surprised how much they can catch up.
