This month me and my boyfriend had protected sex with a condom about three times. It wouldn't be for long, at most maybe 15 minutes, and we'd stop to check the condom each time, and each time it would be in tact. My boyfriend does not ejaculate even though we use condoms, he always pulls out. After each time we have sex, we always check the condom by performing the water test and each time the condoms would be in tact. I am not on birth control, but i am very careful because i do not want to get pregnant. I know there is a possibility and I've been worrying because my period is two days late according to my period tracker. I dis have the flu eariler this month, i read that could delay my period. Any advice would be helpful. Thanks.
