I usually have pretty irregular periods then they will go on a cycle then back to irregular. For 4 months they all started when they should. Well the past two have been crazy out of wack. I usually start around the 16th of each month. And the last one had  been the 1st of November for only about 4 days if that, and I still haven't gotten one for December? My pregnancy tests were unfortunately negative. Idk what could be happening right now 😐 could I be pregnant with no signs? Id imagine i would be noticing a belly or something by now Idk. I hope I don't sound dumb to anyone
