sorry...I meant it sounds like your hormones are out of balance.
hi i think the poster means your hormones are out of balance, maybe!
sometimes your period may be delayed for one reason or another and then come on after sex. but if your not using protection then of course you may fall pregnant or pick up an sti/std
take care of yourself .. if your very worried or think you may be at risk of infection , go along to a clinic if you can..
Sounds like wonky hormones...and/or a possible virus. If you aren't wanting to get pregnant, you should start using condoms. Condoms not only help prevent unplanned pregnancy, they help protect against sexually transmitted diseases. Your partner can have an STD and not even know it. STDs can cause long term pain, disability, infertility and even death. You owe it to yourself to protect yourself. You are WORTH protecting.
