could i have gotten pregnant?

this will sound completely ridiculous so bare with me... my last period was a day off so i know the app isnt 100%. and last night i had a dream i was at the drs and told i was 3 weeks pregnant.. as you can see we had sex the day after my “fertile” day. we use withdrawal only. now you may be thinking “its just a dream” and im crazy but when i was pregnant with my daughter four days before my water broke two months early, had a dream of my c section. everyone said i was crazy there was no reason for me to get one... am i just crazy? cus all ive seen online today is prego talk and im getting scared😂🤦🏼‍♀️
