Currently 8DPO (could be 7DPO), the only symptom I have is extreme tiredness. Did a FRER this morning, got a BFN. I don't usually get any symptoms in my luteal phase, so I know my progesterone and estrogen don't usually make me feel this way. That leaves to be the HCG hormone.
If HCG causes tiredness, then why am I not get a positive test? If the HCG is so low to even get a positive test, then why am I feeling such strong tiredness? Doesn't seem to make sense to me.
Has anyone had a strong symptom(s) while getting BFN, and then getting BFP later?
