I haven’t ever went into labor on my own, last night I lost part of my mucus plug& having contractions. Today they’ve gotten stronger and I’m having a lot of pain in my vagina, butt area. Not really sure how to explain it. Maybe groin area. Anyways my MIL thinks I need to go to the hospital but I’m not sure and don’t wanna go if they gonna just send me home. This is my 3 RD baby. I’ve been having a lot of pressure in my back also. Thought walking would help but only made contractions worse. Any advice would be appreciated!
