I am still none the wiser about how long you take the B6 for and sorry Andi, don't know anything about the aspirin but have read a few more things and thought I should share them with you. Bear in mind though that these are just views of people chatting like us, not experts.
Apparently, Natural Progestrone Cream if you have a short LP is worth considering as many of us have excess estrogen and need more progestrone to balance it out. The reason for this excess is something called Xenoestrogens which are chemicals found in products like lotions, fabric softener and plastics and they mimic the effects of real estrogen. Low progestrone levels are apparently a reason for early miscarriages.
Re the B6 - be careful because a lot of pre-natal vits already contain B6 and 200mg is the upper limit. Signs of toxicity include numbness in your extremities. I have also read that B vitamins only work in combination with each other so it might be better to take a B complex vitamin instead.
Re grapefruit juice - considered to be a nutraceutical food that potentially provides medicinal benefits, although it is also classed as a nutrapollutical as it can cause adverse affects also. The active compound in the grapefruit is furanocourmarin, it appears to block enzymes in the intestines that normally breakdown many drugs, the effect is more of the drug is absorbed into the body. The juice can interact with medicines increasing their potential effect, which can be dangerous, inform your doctor if you consume grapefruit juice on a daily basis. Not all medications react with grapefruit juice.
Finally, oatmeal! allegedly, eating it daily can assist with EWCM - I'm sceptical, I have porridge every day and have very poor EWCM (that said, I was on the pill for 18 years until 4 cycles ago and it can damage the part of your cervix that produces EWCM so maybe that is my problem not the oatmeal!)
