So frustrating!!

My husband and I have been ttc for 3 yrs now! I have been doing everything right trying to get my body to conceive a baby! All I want it to be able to hold it watch it smile watch It start walking,change its diapers,feed it, hold it when it’s crying,look at its little fingers and toes! Smooth it when it’s sick! I want that experience of being pregnant and having feeling the kicks and I know I’ll be scared and I’ll be worried I’m ready for it I want it so bad! It’s so frustrating that my body can’t do what it’s supposed to do! I keep getting to just stop thinking about it. It’s gonna happen. Stop trying. Ok so how am I supposed to not think about it I’m 32 and I know what I’m ready for it I’ll be a good parent and my husband will be a good parent. I’m just SO So SO tired of thinking about it! I want to just scream! I literally trick myself into thinking I’m pregnant every month! Spend so much money on test and think I get positives and then boom my af shows 3 days early! So now I’m gonna try so hard not to think about it! Find something else to keep my mind occupied! I’m just so frustrated with it! Also I’ll attach a picture of the test I took yesterday that is negative but when I took it I convinced myself it was positive and 2 hrs latter af showed!
