Help me

Help me ladies...I’m roughly 5 weeks 2 days...yesterday at work I got up to go to the bathroom...it literally hurt to walk...it feels like I’m pulling muscles at the bottom of my stomach... when I’m sitting sometimes it’s fine...like right I have full ache in my lower back.... no cramps...pain only happens when I’m walking...I sit down at work! What’s going on? The dull ache isn’t bad enough to go the doctor but that pain when I’m walking makes me wanna sit back down...
