Good day! For days, I've been worrying about my missed period. Yeah, although I am very used to it because I always have an irregular menstrual cycle, worry takes over my system because I had my very first sex with my boyfriend. Last January, I had my period on 8th. But now, it's already 20th of February! Please help me. Am I pregnant or just having a missed period? Do I have to take the pregnancy test? Please respond. Thank you very much!
