Hmm... if you ovulated only a few days ago then it would be too early to be getting symptoms. Symptoms usually start as early as a week before your missed period. I would say if you are concerned contact your doctor and request a blood test that way you two can make a plan to stop the pain killers or maybe prescribe something safer. Best of luck to you let us know how it goes.
i have a similar situation....
my fiance and i had sex for the first time a few days ago. i was ovulating, not on birth control, and we used the pull-out method. i'm now concerned i may be pregnant because i also have the very early signs (constipation, minor cramping in the lower abdomen similar to when i'm on my period, etc). however, i take 1.5 pills of hydrocodone/ibuprofen a day for pain, as well as about 2 advil in the mornings. i'm concerned this may cause me to have a miscarriage if i am pregnant?? or that it may harm my fetus? but i can't cut the pain pills out cold turkey! please help!?
Its possible however you wont know for sure until you take a pregnancy test... however the egg only survives for 24 hours and it usually takes about that time for the sperm to even reach it. Chances are small but things happen. Best of luck to you.
