Am I in labour or?


So I’d say the past 4 days I’ve been having terrible lower back pain, today I’ve definitely dropped, had really bad lower back pain that I couldn’t even straighten up or support myself but that kinda went away now it’s been a kind of dull ache but hurts more when I lay down and I’m aching in my pelvis and get shooting pains in my vagina. Just went to the toilet and had a heap of clearish/yellowish discharge with a tinge of pink and now I’m kinda having dull pains in my lower abdomen like period cramps with the feeling like i really need to poop bad. Is this labour??? Also had reduced movement too
