I had my previous periods on 25/11/2023, it lasted up to 4-5 days. On 8/12/2023 I had intercourse with my partner, he used protection all the time and one time he didn't but he didn't cum in me. This month's period date was on 20/12/2026. But I started bleeding on 14/12/2023 morning. Blood is not heavy. It's light to moderate. Till this morning i.e.15/12/2023 I have changed two pads. Normally my cycles arrive on the actual date only. What should I do? Is there any chance of pregnancy? Should I consult any game?
