My dp is at work and I can't contact him until break times. I don't really have anyone else I trust to talk to.
Basically I'm worried I'm pg. We are not ttc, DS1 is only 14 weeks, fgs
. I have been feeling a bit off it but usally do this time it year I tend to be ill or recovering between September and March 
Apart from dp commenting on my boobs looking bigger I haven't had symptoms until this morning I have been throwing up. (also my belly looks bigger, but I haven't been the healthiest lately)
Thing is, my last AF came on 21st October. So my possibly stupid questions are, if I were pg:
Would it be possible to be having sickness so early ? (was quite severe with ds but not quite HG)
Would it be too early to test? Calculators say poas on 20th Nov?
Could I have ovulated early? Had a period last month but still be pg? 
And my last question which sounds really selfish. I have a small night out planned tonight, first one since having ds back in August. If I tested negative today, went out and had a few drinks, then went on to test positive on Nov 20th, would this have an effect on the baby? (haven't even decided what ifs, yet but wouldn't like to take risks)
TIA and thanks if you could actually follow this.
As I say I have no one else right now.
