Am I giving it too little of time??

So I've been on LE diet for about a couple weeks, really strict for one. But I never eat red meat and usually have a low calorie diet to begin with. I've taken ph this week with strips and it looks between 4-5. I just started AF today, my last was Dec. 8 and I had positive OPK on Dec. 24. I would like to try this month to have a Libra baby, but have I allowed body enough time? My DH has started licorice root and I'm taking folic (800mcg), cranberry (1400) and SP. Anything else I should really do to up my chances for TTC girl?

You need to be on the diet and supps six weeks. You also need to test your ph at O. It is normal for your ph to be low other times during your cycle but it will get higher at O. Good luck!
