Last month with my chemical I had a ton of symptoms that led me to test: sore boobs, increased sense of smell, food aversions, etc. This month everything seemed normal for getting my period, including PMS, except I was ravenously hungry.
Last month I was definitely feeling the hcg because I was positive as soon as I had symptoms and symptoms are the classic stuff linked with hcg/pregnancy, but it was such an odd thing, because it felt like "too much" for my pale test line and then of course the pregnancy did not stick. So.... idk, these last two cycles taught me you never really know. You really don't.
