Just curious

Hey friends! So I’m 8 weeks pregnant tomorrow with my second child. This week I just started spotting (light pink). I started having very very mild cramps today. The cramps are so mild that I honestly can’t tell if I have gas because I’ve been very gassy since I became pregnant. I have never had a miscarriage before and don’t know many signs of a miscarriage. Should I be concerned about the spotting? Is this a possible early miscarriage? Could it be something else? I’ll go to my OB but I’m just curious to know what you all think 🤰🏻🥹🥲🙃
