Menstrual like cramps & aversions already?

[hesnotamartyr]

I posted here two days ago when I found out I was pregnant. I'm 4w4d along with my second baby and already I seem to have aversions and cravings. I've been craving meat of any kind and can't stand the smell of alcohol (especially cider). My husband plays in a band so we went to the pub last night to watch him play and while everyone was drinking the smell made me want to throw up and kissing him after he'd been drinking cider made me physically sick. Is this normal to experience them so early on in the pregnancy as with my first I didn't notice anything aversion-wise until I was in my second trimester. Has anyone else experienced something similar or is it all in my head?

Also, today I've been getting mild period like cramps and a heavy feeling in my uterus like I'm about to come on my period. I know some cramping is normal and it's not continuous or very painful nor accompanied by any bleeding but I just wanted to put my over-worrying and analytical mind at ease by asking if anyone had similar feelings early on in pregnancy and how long did they last?

Thank you.
