Well, I started taking B6 last cycle for my LP, this cycle I added B12 because I heard that you need the B12 for the B6 to work the best. From what I can tell you don't have an LP issue, so you're good on that front!
As you know we did SMEP this cycle too. Not much different for our usual BD routine, except adding a few times in around Ov. (We got it in O-3, O-1, O, and O+1 this cycle) but it is still something we tweaked a little bit.
Another thing I did differently was drink a ton of cranberry juice. I heard it can help strengthen the lining so I drank 1-3 glasses everyday (actually still do right now lol).
I also used SoftCups this cycle as well. They seem really strange and bizarre, but if you put them in properly you don't feel them at all. Plus they can stay in for 12 hours.
I think that's about all that I did different this cycle than the other ones.
Edit: I forgot, I also used guaifenesin (expectorant) this cycle as well. I actually used the Up and Up (Target brand) Children's mucus relief. I took 2-3 does of 250mg a day (so between 500-750mg a day). I was using it for a cough for the first 3 days until I remembered reading about the effects it has on CM so I used it for an extra 3 days past actually needing it. The only thing with this is to remember to drink a lot of water. The medicine can't produce mucus, only thin out what you already have, and water can help produce it.
