Hi I was wandering if some woman’s hcg levels can stay low even if there pregnant but it’s so low that it won’t pick up in the blood or urine test. I just went to the er with a lot of pelvic pain and pressure there and they did a blood test and it can neg and I’m having all the signs my boobs hurt they are getting bigger and darker I’m hungry all the time tired moody plus I’m 5 weeks late and I’m reg on my period I’m going for an ultrasound tomorrow hopefully it’ll tell me more
