Is there something wrong with me?!

Sooo I'm expecting and this is my fourth pregnancy but my last two didn't make it.. so this will be my second child.. But I'm having a problem with myself. Let's start off with the fact that my pregnancy during this first trimester hasn't been the best and I have been in and out of the hospital for pretty much all of august. And every time my husband and I were intimate the very next day I would be spotting but I was always told that baby is fine and the heart beat was at 141 bpm. Now I'm still getting morning sickness that I have to take pills for so I can eat but the weird part is - is that some days I don't feel like I'm pregnant and I'm scared that when I go for my babies doctor appointment that I won't hear a heart beat 🙁 is there something wrong with me? Or am I just scaring myself?
