TTC #2 while breastfeeding

I'm going to pull out all the stops this month. Before we're just trying to have lots of sex and let it happen, but that's not working for us. No more messing around with those 5 little green boxes lol. This month (our last month to try for 7 months) I'm taking my bbt, 2 different opks, softcups, prenatals, hubbys now taking vitamins to, no alcohol, eating healthy and exercising. This is our month I can feel it! Or maybe it's all the knowledge haha. Does anyone have any other tricks I can try? ☺️
