Last had sex on 11/5 (unprotected) , on 11/20 - 11/21 I had light pinkish spotting that only lasted 2 days at this point period was 7 days away (never had spotting or bled before period in my life this the first time) i had slight tight feeling that only lasted 3-5 minutes on the first day , on 11/24 i had sore and itchy breast at this point period is expected 3 days away , i want to wait to to test after missed period . Is it a possible chance I’m pregnant ?
