I have been on the mini-pill (Cerelle) for around 2 years. Prior to this I had an IUD (Mirena coil) for around 5 years, and took an oral contraceptive for around 7 years before that. I generally stopped getting a period whilst I had the IUD and continued to have to periods on Cerelle. Occasionally I will have the odd month with slight cramps or minor bleeding. This month I’ve had rather painful cramps, and and a period/bleeding that has been slightly heavier than experienced before. The majority of this has been dark brown, thicker discharge. I’ve not missed any pills in the last few weeks/months (I’ve tracked this and always take them before going to bed at the same time). I’ve had no sickness/diarrhoea in the last few weeks/months. I’m quite an active person with a healthy diet, and I’m in my late 20s. I have a long term partner, and am sexually actively. Should I be concerned that I’m (randomly) bleeding heavier and cramping this month?
