Ugh please help..

Today i would be 5 weeks pregnant, but I'm still getting negatives. Went to doctors office and the test was negative. I convinced my doctor to let me get bloodwork done. Bloodwork was negative. I have pcos and I'm reading online that sometimes women with pcos will get false negatives and dont know for sure unless they get an ultrasound.. anyone have the same experience?

Im nauseated, restless, constipated.. my breasts and nipples are EXTREMELY tender, im crazy bloated.. my feet and hands are swelling.. no af, no spotting, every symptom my mother had when pregnant.. I'm so confused!
