Why not me?! 😩

I’m currently going through a 3rd miscarriage in the last 10 month. Deep down inside I kind of knew it wouldn’t be successful (I’ve been bleeding for almost 3 weeks now) I was still a little hopeful but my Dr confirmed my hcg levels kept declining. I’m almost ready to give up trying to conceive completely. I’m angry, sad, & frustrated. Everyone keeps saying try again, don’t stress, at least your able to get pregnant etc. I feel like I’ve had every test under the sun done, hormones, ultrasounds, blood, everything is always “normal” yet every pregnancy has ended in the first trimester. Please tell me I’m not the only one frustrated with no answers
