concerned

Hey ladies ! So I'm a little concerned and I'm calling my doctor right now I'm just on hold. But last night I only got 2 hours of sleep ... then this morning my fiancé took the dog out and she went missing... this caused me a lot of stress this morning and I went in full panic mode. This dog means the world to me I've had her for 11 years. Luckily our neighbour found her and took her inside to keep warm. He's a nice old gentlemen who apologized for causing stress and worry he noticed the dog walking around and said she looked cold and when he went to tell us he found her we were outside looking for her. So along with this very minimal sleep and stess my fiancé's car would not start this morning. Now hes at work with no car about 45 mins away from me and he made a comment saying "watch today will be the day because I don't have my car." And now I've been feeling nauseous and sick all morning and when I try to eat I just can't I have no want to eat and whenever I try to fall back to sleep I feel dizzy and can't sleep. I'm also having period like pains but I know for a fact they are not contractions. Could all my stress this morning have caused harm to our baby ? Or even cause me to possibly go into labour today ....
