So I'm just wanting to make sure these seem like normal end of pregnancy feelings. My lower back has been a lot more achy and every so often I'll get mild period like cramps. My stomach tightens just about every time I get up from sitting or laying to walk. It's not painful at all and the period like cramps are not everyday. Once in a while I'll start feeling nauseous. Sometimes she puts a lot of pressure on my bladder and cervix too. I'll pee and then 2 seconds later when I stand up feel like I need to go again. Should I message my OB or are these pretty normal and expected? My next appt isn't for 2 weeks.
