I take my pill at the same time everyday (mini pill) and have done forever but since I started the mini pill I get no period but only some spotting about a week after when im meant to get a period - is this normal

Yes. You no longer get real natural periods on the pill so you’re not meant or due to have a period at all. Ideally you don’t bleed at all on the mini pill but irregular bleeding is a common side effect.

It’s ideal you don’t bleed as you’re taking constant dosages
