Pregnancy after chemical pregnancy

Hey ya’ll I’m 10dpo today. Last month I had my first ever bfp and it resulted in a chemical pregnancy. I was absolutely devastated because I had all the symptoms and then it was just gone. This month I’ve had no symptoms except the odd cramp and achy back and then today I’ve been feeling a bit sick. This time last month I was sick also and then got my bfp the next day which would be a month tomorrow. I guess what I’m really asking is can pregnancy symptoms change and is their any success stories of pregnancies after chemicals 😕💕 thanks guys.
