Hi! Take plenty of pads and wet wipes in case a period arrives, as well as disposal bags and pain relief. I found 'feminax' helped, to be taken 2 days B4 a period is due. MayB ask your pharmacist for advice?
My periods waxed and waned for several years. I would miss months then get back into a routine. Throughout my menstruating years I would have a heavy bleed with intense cramps, followed by a couple of days without, then a brown stain - red blood is fresh, brown has been held back - probably due to not enough hormones! I also had an itch high up at that time.
Cramps will be based on your hormone levels.
