I keep getting negative tests. I'm trying not to obsess and symptom spot... but there's a lot of symptoms I can't ignore.

Backstory: last period was June. I have PCOS. Stopped taking medicine in January due to constant sickness. Started metformin back up a month ago. Have been trying to conceive about a year.

BD/Ovulation info: I got a smiley face on my opk September 26 (almost two weeks ago) BD'd every other day during that period. Used preseed.

Symptoms: severely tender breasts, major fatigue, nausea (not morning, random throughout the day but strong), feeling wet but really dry, no af yet, cramping off and on, tightness feeling in Lower abdomen especially on left side, super strong sense of smell, headaches, constipation, can fall asleep anywhere (not usual for me).

However, negative tests every single day. Anyone else have any ideas? My body feels pregnant. But seeing these constant bfns tell me I'm losing my mind. Can some people not get BFP's? Is there still hope?
