Paaain!!!

So it’s almost 10 pm and I am sitting in the bathroom in immense pain!! I’m only about 28 weeks. It’s been happening for a couple hours now where every so often my stomach will get really crampy for about 30 seconds. About an hour ago it started to hurt a lot more and I thought it was Braxton Hicks mixed with the need to pass gas. So I went to the bathroom then went to lay in bed with my husband, as typically laying down and drinking water help my Braxton Hicks go away. They pain however has gotten much worse and much more frequent and lasts longer. My lower back just constantly has a dull pain now. I’m drinking more water and taking a warm bath in hopes that that will help though no luck so far. I don’t think I could be in labor as I’m only 28 weeks and I haven’t had my water break or anything like that. I also haven’t had a very concerning pregnancy but this is also my first pregnancy so I’m not sure if I should be concerned about this or if it’s just a different type of Braxton Hicks?? They hirt so bad I can’t talk and have to brace myself in pain! I don’t want to say anything to my husband because I don’t want to worry him if it’s nothing but has anyone else experienced this at 28 weeks?
