Hello there. I'm 21, facing irregular periods, sometimes with a gap of 3-4 months. Consulted a doctor nearby. He gave me tabs. Periods started then missed again for 2 months. In March almost bleeded for 13-15 days, terrible! And then in april, just one day and nothing after that till now. Is that my body weight bothering or some other reason? I got intimated with my partner last week, any chances of getting pregnant if I'm facing period problems? I'm really concerned, Don't know what to, Help.
