First month of trying

Hey there ladies I’m 24 with two children a 6 y.o and a 2 year old after my 6y.o I had two miscarriages back to back both at 8 weeks and I thought I could never get pregnanct again and than I had my son perfect pregnancy .. we just started trying again this month meaning my ovulation day is in 5 days I bought opk tests each time I got pregnanct we tried the first time and got pregnancy right away but my mind is telling me I won’t get pregnancy again it’s crazy ! I’m praying the outcome is good and I won’t miscarry again even though last was successful
