Has this happened to Anyone else

Shiniqwa.

I miscarriaged on June the 20th and was very disappointed behind that. I was test till I got a negative test and the last negative because I didn't get my cycle at all in July so on the 23rd or 24th I began to get negative test! After that silly didn't get my cycle so I tested today and got a positive. I don't know how to feel right now. I want to be happy but my nerves won't let me 😩
