Hi. I’m a little confused. My boyfriend and I had sex using the pull out method( I know not 100%) last Monday the 18th during ovulation ( I had the egg yolk discharge). That Friday I started having lots of aches in my lower abdomen and back aches that lasted all weekend into this week. I still have mild aches and headaches. I’m. It suppose to start my period until next week maybe the week after(usually between the 8-13th each month). I don’t normally cramp and if I do it’s usually right before. This morning I took a preg test but it’s neg but might be too early. Help
