Has anyone else...

M 🌻💕
Hey there so I'm pregnant with #2 and honestly don't remember this feeling from #1. But has anyone else felt pressure in their pelvic/vag area, almost a little sore? Especially when sneezing, or sitting down, or squatting to pick up things from the floor... I am almost 16 weeks. And one more question, I saw this posted before but (TMI) I've lost a chunk of thick mucus at least once a day for the last 4 days. Normal? It's like when I lost my mucus plug with #1 but I'm obviously not close to giving birth. TIA. :)
