No bleeding after sweep

Catherine

39 weeks today, second pregnancy. 4 cm 70% effaced. Had a sweep done from first time ever at my appointment 3 hours ago. I didn’t bleed at all when getting it done and no spotting yet. It didn’t hurt that much either. Anyone have similar experience and it still work for them? I was just expecting it to be more uncomfortable and I’ve had cervical checks earlier in pregnancy where I bled so seemed weird there was nothing!
