Is there any naturally occurring event that happens every 3 months or has 3 month cycles?

Indeed other mammals do have periods or seasons and indeed this is closely connected to fertility and sometime being "in season" or "on heat". However across the spread of mammals alone there is a phenomenal range of differences. For example the lifespan of some small rodents is less than the gestation period of an elephant. Curiously a species to which they are closely connected.\nFemale kangaroos virtually exhibit all the stages of the reproductive cycle at once, fertile, pregnant and raising young.\nIn short mammal periods do happen but don't generally conform to human monthly cycles.

It's natural, but not all the time...\nAnd it depends what do you mean "all the time"

Actually, since a full moon happens about once every 28 days, in a 365 day callender year, it can happen anywhere from 12 to 14 times.  However, neither of those numbers are precise, since the rotations don't divide evenly into 24 hour days.  The real number of the period of the moon's rotation into that of the earth's is something like 12.95

It's a normal part of the natural cycle.

Technically, 3 (I think).\n\nAn eclipse happens when the Moon's orbit intersects the Earth's plane of orbit around the Sun AND the Moon and Sun are in the right place.  The first condition happens once each Lunar cycle, while the second condition happens twice in Earht's orbit around the Sun.  But since these cycles don't correspond exactly to 1 month or 1 year, it can technically happen 3 times (I am thinking) - at the start, mid and end of the year.

I would say the earth needs less energy to heal, wouldn't you? Anyway I don't think there's a coincidence there. Lot's of things happen on random similar dates. After all, there's only 365 of them, plus one every four years. That's not really incredible odds.

Uh, in the third tri-mester?  I'm having a hard time figuring out when pri - mortal begins?  Conception?  Third trimester?  Birth?  Geez, this is a toughie.  Why, I'll wager there are lots of folks debating this topic all over the world.

In my experience this has happened before but not often. usually my next cycle is normal and usually it happens if there is alot of stress in my life. I would not worry about it, you cannot be regular all the time.

A woman can get pregnant at ANY time of the month, ANY time of the year.  \n\nAfter menopause, the probability decreases dramatically.  That or if the woman has had a hysterctomy (removal of her reproductive organs). \n\nUse contraceptives (condoms), if one must have sex.

The moon.  Every four weeks there is a "New moon."

Interesting observation. Pure coincidence ~ unless you want to make a big deal out of it.  These things happen without being planned. History does repeat itself.
