Hey girls will join you on the obsessive symptom watching!
I've had nausea (pretty bad at times which has stopped me eating), tiredness (but always feel tired!) and sensitive nipples (like I don't want DH to touch them). Now on 19DPO but still getting BFNs

I reckon it's just my cycle playing up as it has done since I came off BCP in Jan.
Also - nausea seems to have gone now which is annoying!!
