Yes unfortunately docs will always seize upon nursing as the reason for cycle issues and while that can be true sometimes, more often than not it's completely unrelated and you could get pregnant while continuing to breastfeed just by having patience and allowing your body to sort things out at its own pace.
Many doctors are not that knowledgeable about what causes short LP to be honest and will say all kinds of things that really don't seem to add up with our experiences. I've seen it happen on every continent but Antarctica now, LOL. What we are doing online is amassing a much greater body of information than medicine ever has about the workings of our bodies and so I urge you guys to take what your docs say with some skepticism because too many people are getting information that is actively untrue for me to accept what anyone's doctor says about LP.
What happens with your LP is that your body operates as if everything is normal. You will ovulate, have EWCM, your cervix will act normally, and this goes on as long as your body can manage it. But when it runs out it will just pull the plug sooner to save up resources. Like I said, you can get pregnant with an LP of 9 days, so your body has given it a shot to conceive and if it doesn't happen and it either a) runs out of "fuel" totally or b) doesn't receive the right signal that a pregnancy has occurred and feels like it should "save up" resources for next month instead of blowing it all making estrogen for 5 more days for a pregnancy that hasn't occurred,
It is just like how your car runs totally normally till practically moment you run out of fuel. Now some women are SO low in estrogen that they'll have symptoms all thru the month but that is not always, or even usually the case. Most people have ~mostly~ enough estrogen to make it through ovulation and a few days beyond, but just not quite enough to make it all 14 days. So you can go right through ovulation and for 7-10 days after that with everything being perfectly normal, and then your body is just either not able or not willing to expend any more resources keeping the lining going for a pregnancy it doesn't think has happened.
I usually wait to see if the dairy and eggs work before we try the salmon, I think I hadn't advised you to do that yet but if you want to try it, that's fine!
