Weird symptoms??

I can't eat anything with out automatically feeling nauseous and like throwing up, the only thing Iv been able to keep down is chocolate milk(weird right???) Iv been super congested and I have a sore throat but NO OTHER COLD /ALLERGY SYMPTOMS, I don't feel "sick" just off.

I'm super tired all the time and Iv had some weird lower abdomen cramping that's way to late for ovulation and way to early for a period (normally get period cramps the last 2 days of period) my husband told me that these could be extremely early pregnancy symptoms that happen during/right after implantation (he's been obsessively educating him self so we can have a baby lol) is he right? Have any of you ladies had any similar symptoms and been pregnant?
