Am I pregnant

I had a miscarriage on oct 20 I was 5 weeks. Had no idea I was pregnant I had signs but I was too busy to acknowledge them. A week after my husband and I started trying again since the doctor told me I have a higher probability of getting pregnant and have a healthy pregnancy. It's been over more than 2  weeks I am not sure, but I have been extremely tired and headaches every day. I also have cramps I am not sure if it's because I might be pregnant
