18 weeks and yuck

I don’t know how to describe it but I don’t feel right. I got sick earlier and went to bed but tossed and turn. Couldn’t get my belly comfortable. It’s tight and aching. The inside of my vagina (?) is sore and I am spotting, but spotting happened a lot for me. I’ve got slight cramps too. I went in to see my dr today and my cervix looked good and long she said. I haven’t felt right the past 2 days though. Maybe it’s in my head but I would hate if it wasn’t.
