2 weeks ago I had unprotected sex with my boyfriend on the first day of my period by the next night it was finished I'm a little worried about it as I've always had a regular 4 day cycle. I'm honestly a little behind in knowing whether I should be worried I'm pregnant or not as I grow up without a female influence, dad tries but I'm not comfortable going to him with this. I've felt a little weird for the last few days. Any advice or help would be appreciated Thanks
