Could i be pregnant?

AF was on nov.6th and ended the 12th.

I have been doin the baby dance non stop since the 21st which is close to my ovulation date. I have PCOS but was told in 2011 that they disappear when i have my periods.

I have been ttc for 2years. Nothing..

I have been hungry like i could eat a hippo!(; i am loving cucumbers which i abesoulty HATE them but now i like them. I have to pee alot. One app said my period is suppose to come today 12-6-14 but then glow says itll start 12-10-14. Not sure which one but i am conspipated so i have conspipation cramps but not period cramps.

My ovaries are hurting too.

Also been getting headaches which i normally dont get..

Should i test?

*also has anyone tried pre-seed from walmart?*
