Pregnant and cramping?

I just found out I was pregnant I thought I had gallstones but when I went to the ER, they told me I waspregnant! I’m super early right now (first trimester and perhaps only 2 weeks in), but this morning I was bleeding and now I’m in pain. I went to ER and they said I could either be having a miscarriage or having implantation symptoms. Any ladies out there went through the same thing I did and turned out fine??
