We are TTC #2 and I'm frustrated. With #1 I had long cycles off of bcp and short LP (ave 8 days) managed to get pg but wouldn't have know if I wasn't temping as I thought my period had started but my temp stayed up and had an uneventful pregnancy. This is cycle 2 after iud last cycle was long and an lp of 5 days. This cycle I o'd on cd21 it's a miracle but now in cd1 5 dpo. Come on. I'm headed to my acupuncturist (also a CNM who does a lot of acupuncture for fertility) on Saturday but if this crap doesn't straighten out in the next cycle or two clearly some blood work needs to start. I do take vitex and b6. How long would you ride out this short of an lp given I have in the past had a successful pg and no know m/c? I know two cycles is nothing but an lp of 4/5 days is clearly not going to get me anywhere. Maybe mirena is still screwing with me.
Re: LPD
Your body might take a few months to regulate after Mirena. How long were you on it? Did you have periods while on it? I would say you should TTC for a year before having blood work done unless you are over 35, then consult with an RE at 6 months.
I agree that two cycles is too short an amount of time to go for testing or knowing if your acupuncture has worked. I had a short LP coming off of BC (the nuva ring), but it eventually evened itself out. I'd ride it out at least 8 more cycles (a total of 10) or so, especially since you've already gotten pregnant with a short-ish LP. Give your body time to regulate itself before worrying.
ETA: I should add that I often didn't have periods at all on the nuva ring, and my doc at the time thought my lack of periods on it could be connected to my short LP coming off of it.
