Trying not to get my hopes up

So husband and I have been trying to conceive for 2 years. We have been pretty upset the last couple months because we are in our early 20s and I feel like a failure by not being able to conceive. I think I’m just hopeful because it was the first time using opks and seeing a positive of any sort. Today is pos ovulation day 8, my boobs are a little sore (normal for me), nauseous, feel funny in general , odd little cramps here and there, oddly positive this month (normally I am fairly sad and out of hope). I also have had these little signs here and there. The day I test in hopes for my bfp is on Mother’s Day which is also my husband’s birthday. He will sit by me and absent mindedly put his hands on my stomach or when he’s sleeping do the same. I catch myself doing it too. My friend is convinced I’m finally pregnant but I can not let myself believe anything yet because I’m afraid of being absolutely crushed again. How do y’all cope with wanting to be hopeful but not wanting to set yourself up for devastation at the same time. I keep telling myself all my symptoms are either pms or maybe I’m coming down with something just so I don’t get too excited...
