I've also recently started having cramping ( I'm 12 weeks)And I also lost my baby in July due to a mc I was 7 weeks. The doctor says it's normal to have cramps when your pregnant as long as your not bleeding. I'm not sure if you had the same but when I had my mc I had full on contractions like I was in labor and where I felt like I had to push and I obviously bleed a lot. I ended up pushing the baby out. So with that said I know my body and I know what a mc feels like everyone is different too though but if your not bleeding that's good! I would be worried if you were. But go to the doc so you can ease your mind. Hope that helps.
Since you had a miscarriage in the past dont wait and go to the doctor.. Please dont wait for something bad to happen is always better to be safe than sorry..
