Agree with Sarnie, don't give up Jakey.
I've not been on this thread for long so I don't know your whole ttc story but are you sure you're ovulating? And are yoy dtd often enough?
I'm having a bit of a shit day myself. AF arrived this morning, meaning that this cycle was only 29 days instead of the 42 I had in my last cycle. I guess the positive thing is that shorter cycles mean there are more of them quicker and therefore more fertile days. BUT and this is why I am upset, if my ov tests were right and I have no reason to doubt them, my luteal phase this cycle was only 4 or 5 days, catastrophic!
So I did some more research, and then some more and even more and what I have come up with for the lenghtening of the lp is the following:
-vitex (agnus castus)
-vit b6 (as mentioned by Jakey)
-raspberry leaf tea
-progesterone cream
-diet changes (no alcohol, caffein, chocolate, high fat/high sugar foods)
-loads of veggies, fruit, wholegrains, complex carbs
-vit C
I'm not sure how safe the vitex is when breastfeeding as there is conflicting information out there and I certainly think the progesterone cream sounds dodgy but I've not researched that.
So I bought some Vit B6 today and have started to take 50mg with my prenatal vitamins. I'm also drinking the raspberry leaf tea. Will see what that does to this cycle and the consider adding vitex from next cycle.
Feeling very down about it all. I wonder if there's a chance my lp will get longer by itself...
Hope everyone else is having a better time.
