So, I posted a while back about missing one if my cycles, and that I'm usually a really regular person. My other half and I aren't ttc, however things happen in the heat of the moment etc etc. Anyway, I'm now 2.5 months behind on my cycles, I went to the doctors early on and neg, all my hpt's are also neg. But with the time frame it would put me at around 10 weeks if it was possible. Now I haven't really had any signs, except being tired but that's hard to tell if its through work as I work really long hours. Apart from the past couple days, and my nipples - not boobs, just nipples are really tender to the touch - in the sore kind of way. Its probably nothing, and I've done another test but again, its neg. So I'm quite confused. Dr said my cycles are off and should return whenever - but I'm not stressed, not lost weight in fact I may have put in a couple pounds as I do like my food. So my question I guess is, is it still possible to have a negative test this far in if I was indeed pregnant?
