Question..?

So yesterday I had my cervix checked for the first time by my midwife and she said she irritated my cervix and that I may spot. This was around 3:30pm yesterday. Well, I cramped all day yesterday but no spotting and I woke up to go to the bathroom at 5am and still no spotting. However, when I got up at 9am, I had spotted just a little bit on my pantiliner but nothing got on the toilet paper so apparently it had already stopped. Is this normal and ok? I'm just surprised that it didn't happen until so late after the cervix check. Also, I'm 35 weeks and 2 days and was told yesterday that I'm 1-2 cm dilated and 50% effaced and she could feel the baby's head.
