These are all symptoms of pregnancy, however they are all also symptoms of the pill.

yes I know it does stink! If you were pregnant, it should be showing up by now on a hpt. I think it's 2-3 weeks after conception for the HcG to show up in your urine. I think it is safe to say that if you are on the pill and you use condoms you are not pregnant. How long have you been on the pill and which pill are you on? However, if it is really bugging you, I would say take a ride over to your dr.
Keep me updated!
Hope I helped!
