Miscarriage????😭😭😭💔💔💔

I don't know if this is the right place to post this. Me and my bf found out I was pregnant in March 22 and today I am 8+3 but I started spotting Monday, Tuesday I spotted but it didn't stop and then it continued to Wednesday and the spotting turned into bright red and it flowed like if I was to have my period. I called my dr's office Wednesday morning and I have scheduled an appointment Friday to go and get some tests done and then go back Monday and do the same. I'm really scared and I don't want to lose this baby. This is our first baby and we have been ttc 4 mths before we found out I was pregnant. Can anyone help me get through this?
