Early pregnancy symptoms?

Hi ladies! So im due for my period in 2 days. Sometime last week i had a problem with constipation & lots of gas. The last 2 days every night i would cry for no apparent reason & also peeing alot at night before bed also. My fatigue has been horrible for the past 3 days also. Im not sure if these are just abnormal premenstrual symptoms because I just quit my job & i was stressed out... but they arent my normal symptoms before my period. Any advice?
