I had unprotected sex 5 days before period was due. I got my period on 13th May which is one day late then expected date. Last period 17th April. On avg 24 days cycle. Its scanty period. While period is scanty. I can only see blood cloths while I urinate and no signs of light bleeding. Pls advise if I can consider this as regular period or there should be something that I have to worry about.
