Well im 15 and im on a birth control pill ortho tri-cyclen lo and ive taken it everyday on time since august 2004. When my boyfriend came into town, I had protected sex*he wore a condom* with him once on the 28th, once on the 30th, and 3 times on the 31st...I had my period on the 13th n it lasted like regular, 4days. Yet, I feel really bloated lately, and I did wake up in teh middle of the night with nausea, also ive had pains in my abdomin...On the 3rd of february, 6 days before my next period is scheduled to come, I had some brownish discharge and cramps...Could I be pregnant? Or is it all in my mind? Plz help
