I started taking the pill 3 weeks ago and I had a period on my due date for that month but when I came off I started to bleed again for a day then went off and I started to bleed again today but when I put a tampon in nothing was on the tampon and I had it in for 5 hours. Is this normal or should I be worried? And also should I have a period when I’m on the cerelle (not the combined) pill
