My boyfriend and I had sex for the first time three days ago. We used a condom and he said it didn't break and "it filled up all the way". Two days later I was feeling dizzy, lightheaded, and felt some knots in my stomach. I still am today, but I feel like maybe it's just me making myself feel nervous.

It's too soon to be sick from pregnancy, but not too soon to be worried about condoms as birth control. The failure rate is 19% from all condom BC, whether it's breakage, pinhole leaks, spilling over, or who knows what else. The pill is much better and the pill patch best of all.

You could be worried about pregnancy or parents. You could be ashamed or guilty. You could be unsure of this particular man and how much you want to have sex with him. You could have a little intestinal bug. Do a lot of reading on this topic here, under Pregnancy.

Condoms don't always work you should be on the pill its more safe then a condome becauce you could make little whouls in it but you wouldent feal any symptoms of pregnancy in that little bit of time

Hope This Helps.

To pookamook147: The only worry I have about birth control is that I am a Type 1 diabetic, so I don't want the medicine affecting my blood sugars in a negative way.

As noted, the term "filled all the say up" does the boy or man know how to use them properly ?
