Hi, we're TTC Baby 4. I'm experiencing a short LP after BF for 12 months. I'm on my second AF after weaning Baby Three. My last cycle was our first attempt to conceive, and my first experience with an OPK. AF was FOUR days early...I'm 34 and my DH is 44, so I feel a lot of pressure to conceive quickly due to our ages. I wanted to know if anyone knows how to track LP. Do I count day of O as first day of LP, or the day after? I have read about Vitex and was interested in any input on that. Babies 1 & 2 were conceived on first try and Baby 3 took five months, I think it was short LP, also.
