Confused beyond belief! Help!!

Very tired, backache, sore body, cramps/twinges, gas.

Hating the tww.

So I'm around 5-9dpo.

9-7 days before period, probably progesterone but who knows?? Last Saturday we had sex twice and again one time around 1:30am. well IF it works I'll know by the end of the month, but how likely are my chances, I dont even know WHEN I ovulated? That day (last Saturday,08/11/18) I had a big glob of EWCM, although my CALENDAR, said I O'd around the 14-15th, so I'm not really sure. I dont use opk's,temp or anything like that as I forget and get confused easily.

Thank you, any advice, tips or suggestions will be greatly appreciated.

Baby GLITTER to all❤

08/20/18--08/21/18

I'm POSSIBLY 10Dpo , as I believe I O'd on the 11th, so just a few days early.

Yesterday: Dull AF like cramps on and off all day,fatigue, extreame back pain, sore body and headaches and a few days prior.

Today: now I'm getting nothing really? Except vvv slight dull "cramps" that only last about a few seconds, no where like yesterday, my head hurts every now and then, my bbs are starting to feel a SLIGHT dull soreness and I'm just MAINLY tired. 7-8 days until AF!!
