feel like shit

Please no mad comments I feel awful and scared as is but if I'm pregnant it could be one of two.  I pray it's not my ex..that's all 4 days till period.  I won't go into detail but I made a bad mistake of being back with him for 4 days.  Please pray ladies I'm not a bad person.  Out of selfish reasons I had to see why I was so back and forth over 2 men.  I'm with the right one.  I want to be pregnant but scared it would be the exes who is a homeless loser who used me for 2 years.
