Chemical pregnancy

Ashley

Can someone explain to me in more detail what a chemical pregnancy is? I had a terrible experience with an NP that did not explain it well to me. I had the chemical pregnancy last month. I am in my 2 WW now at 2 DPO. From your experience would you wait to test until you miss your period after a chemical pregnancy? (Being that if I did not test early before and get the pregnancy positive I would’ve have known I was even “pregnant.”) I keep going back and forth because part of me feels I should know it I keep having chemical pregnancies but the heart break was a lot to handle. Thank you in advance.
