Ok thanks atomic, will look into the brewers Yeast and NYF.
Ok we decided to give this cycle a miss as we were really exhausted and didn't want to risk that being a factor. Should my husband still carry on with the extra zinc and multivitamin? Just incase you said to carry on as we were due to try imminently or is it ok anyway? Also in my multivitamins I have 20 micrograms of vitamin b12 and I am also taking an extra 10 micrograms is this ok? Being as I am vegetarian?
Ok will trial out the preseed when we aren't trying is it ok to use it with a condom?
Also I noticed that when I used my wondfo OPK this cycle at 9pm on CD12 it was positive, i know you said if I wanted to follow the timing method to test in the morning and if it is positive to try that night - on my trying cycle if I have a positive OPK in the evening would it be better to try that evening or wait until the following day in the evening if I want to follow timing? Note before that positive I had the flashing smiley on the clearblue that morning and the wondfo had a faint reading.
