Feeling different

Hey ladies! I’m 36 weeks and 1 day today and I’m just feeling different today, my stomach is MUCH heavier today than yesterday , i feel kind of nauseous , a “crampy “ feeling in my lower tummy area all around to my back. Is this normal ? I’m fearful of going into labor lol my husband is out of town till the 17th and I want him here for the birth of our first child lol so I’ve been on google all day praying I’m not about to go into labor 😂
