Sorry to sound a bit dim, but...
I often have quite long, irregular cycles (more so pre dc) which the last few months have been 33-35 days long.
This cycle I tested at CD33, because I had sore boobs and persistent nausea. BFN on a FRER.
Retested on CD 40 as symptoms hadn't gone away, and got a strong BFP straight away on a FRER.
On the packet it says it is sensitive from 6 days pre-period, but in that case why was I getting such strong symptoms on CD 33? A cycle of 40 days is very long, even for me!
Normally the ms doesn't kick in till 5-6 weeks for me, and then it gets VERY bad (HG), so I'm feeling a bit puzzled as to whats going on. Its now 10 days since my BFP and the sickness hasn't ramped up yet, just stayed at a constant low-level nausea. Whats happeneing?
Any opinions gratefully received!
