37 weeks and miserable

So I just want to know if it sounds like I could be close to going into labor lol. Last week at my appointment I got checked and I was 1cm and a half dilated (which is half more than I was my first go around) and then me and my fiance got it on not too long after the appointment and after that I had really bad back cramps and my stomach kept tightening... well I had maternity pictures that day too lol. Walking kinda eased the pain when I wasn't walking I was bent over.. that was Last Wednesday. Past like week before that I started to feel like blah. The day before that and since then if I eat anything I've been getting nauseous I'm mostly constipated and just in general feel like crap. Starting Wednesday I've been waddling like a duck and since yesterday it hurts to walk or be on my feet. And my pelvic bone feels like it's going to pop when I try to roll over and I swear I can feel his head in there when I walk just grinding up against my bones.

My mom swears I'm not making it to my due date cause there is a full moon coming this weekend lol but who know..

I'm just putting all of this because it's been 2 years since I had my daughter and with her I was miserable almost the entire time lol I also had to be induced with her. I was stuck at 1cm since 36 weeks with her and got induced at 41 weeks so I don't really know the signs of labor or what real contractions feel like (even though Last Wednesday they felt real enough to me lol)
