I get the same thing and also on hrt and vagifem. I was referred to a gynae and just had a scan. Mines to to va, the vagifem dose I'm doing, 2 twice a week isn't enough. I too like you were scared and worried. The gynae told me if it's just a bit of spotting now and then it's not cause for concern but anymore would need to be investigated further. Get it checked out if your still worried. I'm the worlds worst so know how you feel. X
