I have always been good at taking my pill (mini pill- progesterone only) on time within 30 min. The last few months my period has been coming earlier and earlier, not by a lot, but a few days where I first started getting it around the 19th of each month and now I’m getting it around the 30th. It’s been 4 weeks and 2 days exactly now and I have no signs of it coming. I can’t imagine I am pregnant because of my timing but definitely a scary thought. Is this normal?
