You make a really good point pooklet123. same thing happened to my friend. She tried all these different things but didn't get pregnant until She stopped trying.
I'm no expert, and this is purely anecdotal, but I've found people I know had an easier time conceiving if they "stopped trying". They just stopped thinking about it, and it happened. Lots of children are conceived on vacation for that reason! Everyone is more relaxed. Also, having that happen in July, your body might not be ready yet. You're young, I don't think there's any reason to panic quite yet. I know someone who had to pay $10,000 for IVF, when there was absolutely nothing wrong with her, she was just normally a high strung person who was trying too hard and thinking about it too much.
