Second time mama

So my daughter is 19 months old and she was breech 27 weeks on so I never went into labor or anything with her. I had a very smooth csection. This time, I'm almost 35 weeks and my son is head down and I've noticed a lot of sharp pains near my vaginal area and even my anal area. Is this normal? I felt like maybe since he is head down, he is pressing down on everything. Is this a sign that labor could be soon?
