Aches and pains

Just curious if this stuff is normal, this is my first pregnancy and of course everything freaks me out a little and I don’t really know what to expect at this point in my pregnancy. But I’m 34 weeks, the last couple days I’ve been having period like cramps and some lower back pain, kind of just achy and dull. As well as a lot of abdominal tightening, but nothing consistent or regular. Also having a lot of pressure in my hips and pelvic area and sharp pains ‘down there’.
