Question

I know this is dumb and I should know this.

My ex and I have been separated almost a year. Recently we had sex. It’s been a months. We have done the pull out method. Stupid I know. I had thought I started my period Friday. It ended that same day. And I haven’t had one. Now I have no symptoms of being pregnant that I have had in the past. I know that every pregnancy is different.

Weird thing is I have had no discharge at all for the past week. What would that mean? I know when you’re pregnant it is white and a bit thick.

I guess my question is if you go from not being sexually active for a more than 6 months than start again, can that affect your period?
