Ok I'm really really worried, about a week ago I had my period and obviously I was on sugar pills I had finished after about 5-6 days but I kept taking them for 7 days, then the fist day back on active pills my boyfriend and I had unprotected sex, and I have end of year exams coming up this week and I'm not sure if it's just nerves or what... But I've been nauseous all week and really tired to the point of needing to have a two hour nap, and headaches...I also have swollen glands (not sure if I'm just sick) or possibly pregnant. I'm to nervous to take a pregnancy test because if I do it will distract me from my exams. Someone help 😩😩😩😩
