Stomach dropped... is labor near?

Only 33 weeks and my stomach dropped when I woke up this morning and has stayed low all day. Even my husband thinks my stomach looks crazy low. Freaking out that this could be the lightening and that labor is near. Also have increased appetite and increased peeing frequency. Feeling baby move super low when she was in my ribs. Discharge changed from whitish to completely clear and watery. What do you all think? Labor near?
