Hey my period is 4 days late. It’s been a really stressful 3 weeks and I had unprotected sex but used the method of withdrawal and I’m pretty sure that he did withdraw as I know my boyfriend and trust him, so I didn’t take any plan B.

My cycle is 35 days long and I had sex from the 4th day (November 9) to 8th day (November 13) and my ovulation day was November 30. Yesterday and the day before I took pregnancy tests which both were negative. Then why hasn’t my period started yet? I need help:(
