Light pink spotting & period like cramps at 7 weeks

I’m about 7 weeks pregnant (I don’t have my first appointment with OB until 9 weeks) and last night I started to notice that i was having period like cramps in my lower back. When I woke up the cramps were gone but came back by the after noon and haven’t gone away. Now I’m having light pink spotting when I wipe. Trying to stay positive but I’m starting to worry. I’m trying to make sure this isn’t anything urgent before I have to call the emergency line for my OB office (since it’s the weekend and they are closed).

Has anyone else experienced this and what was the outcome?
