2 day period?

Its like since I lost my virginity in January my periods have been 2 days. I spot first then have a consistent flow for 2 days, then maybe another day of spotting. I haven’t missed a period though so I figured I should be fine if I’m getting a period at all. Anybody else have a short period like this? Do you. guys think I’ll have fertility issues when trying to conceive? Please help me and tell me something! I just turned 20.
