Alcohol withdrawals or early pregnancy symptoms?

I've been an alcoholic the passed year nd have recently quit cold turkey,  last time I tried cold turkey I suffered two cardiac arrests and 3 siezires but I also have epilepsy 
Now I'm feeling agitated, getting sick every day at the same time and feeling very tired plus head aches
I'm unsure whether this is due to me quitting alcohol or if I'm pregnant (I quit drinking because my partner and I are trying for a baby) 
So confused just need some advice before my gp app, can anyone help?
 I'm also feeling little bubble pop feelings in my lower stomach
