Confused, need help!

For these past few weeks I have been getting slight nausea which lead me to take a pregnancy test. It was a very faint positive but positive none the less. I was at leas 6 days late for my period or so and now I'm starting to feel cramping. Is that normal this early on. Nothing too major more like period cramps. They're here for a lil bit and then they're gone. I had a MC last year at 4 weeks right about how far along I should be now. I'm scared that it might happen again. Please if someone has had this happen to them or give me your thoughts please would help a lot. Thanks.
