Trip to l&d at 22 weeks

☆¤Mama Gemini¤☆ • Happily taken mommy to 2 beautiful (1 autistic) boys Nicholas (7) Matthew (3) and our beautiful and only princess Journee (8 months) and we are expecting our last baby also a boy due May 8th 2017
So I woke up about an hour and a half ago to see extreme lower back pain. I went to stand up so I could go to the bathroom and the pain just intensified and then I noticed alot of pressure in my vaginal region as well ages some very sharp and tight pains in my lower left pelvic area. These pains have brought me to tears. No bleeding so that's good. I had placental abrupture at 29 weeks with my 2nd child and I had to be resuscitated twice during the emergency c section. This is my 6th baby so pregnancy is not new to me. I called my on call obgyn and he informed me to either come into L&d now for an evaluation or to come in to my doctors tomorrow. He did tell me that at this point my baby is considered non viable and if something is wrong there's nothing they can do for him. I'm going to L&d now but I can't stop crying and thinking that I might lose my baby. I feel guilty because I've worked so much (2 jobs) and in between all I do is sleep. I can't help but feeling this is my fault. I have severe anxiety so that's not helping me any. I woke up my boyfriend and he's getting ready to take me but he's not acting very concerned and he thinks maybe I'm over thinking. I just hope everything's ok. Has anyone experienced this before? I know aches and pains are pretty common but these brought me to my knees and had me in tears.
