Im pregnant and scared about fasd

So i just found out today, an hour ago im pregnant. I tried to about a month ago, felt pregnant, took an early test 5 and 4 days (one w a small faint line and the second day, completely negative) i then begain my period andbit was absurdly heavy. And now this month i took a test cause my period is 3 days past due. Ive been stressed out and wasn’t planning on trying for a kid after last month, i was giving up. And now ive drank atleast 3 bottles 750ml and (2x) 1 liter by myself in the course of 2 weeks maybe 3 max, some days more than others…. Do you think my baby will be harmed
