Hi, I usually have 26 day periods (I have a 13 month old and my periods came back 8 months ago) and TTC. I'm now day 31 and experiencing nausea, massive tender boobs, and feeling very lethargic. I'm getting BFN and no idea what's happening. Last time I had major morning sickness for the first 2 trimesters, so I'm taking my nausea (I've vomited a couple of times over the last 2 days) as a sign, but I'm testing neg. Any tips/explanations on what's happening?!
