You are totally pregnant. You have three STDs, of which none are curable. The air you exhale has infected your family. Also, yes, your world is over.
Actually, light periods, provided it didn’t come out of nowhere, are “fine” in many cases. A lot of things factor into a cycle, including things like diet, medication, stress… even how much water and alcohol you’ve consumed during the cycle. The best thing anyone could suggest to you is to simply use a home pregnancy test. I cannot vouch for the result quality, however, I happen to know they can be obtained for as little as $1. At that, you could probably afford to buy two or three of them just to put your mind at ease over pregnancy.
Condoms really are there for the whole “safe sex” experience… that is, protection from STDs, pregnancy and so on. Don’t go for flavored condoms for God’s sake, that’s a whole world of sugar and artifical crap you don’t need going in your… well, vagina-hole. Don’t double up on them, as they’re designed for latex (or whatever) on skin friction, not latex on latex… that will lead to ripping, tearing, earthquakes, temporary paralysis, and death.
Death.
Death.
Death.
Actually not really, but it could increase the failure rate of the condom. I’d also suggest that you get on birth control, if you are not already… that’s kind of your own personal “insurance” in the event someone wants to “slide it off” during the event without you knowing it.
I’ve had sex with close to 60 people in my lifetime, and with them, I’ve worn a condom on perhaps 6 occasions. That’s a personal choice, and yes, I’m at a much higher risk than you were, however, I don’t have any STDs and any children because I’m also ridiculously hard to “please”, if you catch my drift. I’ve never been able to actually “finish” with any of those partners, save for my current girlfriend… which is why I love her so much.
Plus she has a personality or whatever.
More if you need it.
