No PMs or pg symptoms

I am 12 dpo and on cycle day 38. My cycles have never lasted this long. I usually have ovulation symptoms (very sore and swollen bbs, extremely high sex drive, watery cm). This lasts until AF comes. And a week before AF I get very irritable. This month, no ovulation symptoms except very watery cm. Sex drive has been practically not existent. And no irritability at all. Instead I have been wanting to cry about everything. Additionally, I’ve had watery cm that keeps getting heavier (heavy, clear and somewhat gummy), I’ve also had severe constipation (sorry tmi). I had dull cramping and back aches on and off in days 8,9 and 10. I’m guessing I’m not pg, so I’m curious as to what’s going on with me.
