Orthotricyclinlo symptoms and conditions

i am on the first week of my second pack, after switching from orthotricyclinLo (which i loved, but my gyn suggested i switch so that she could give me samples while i was abroad). a few days before my first "period" (if you can really call it that...it was ridiculously light as far as periods go)at the end of my first pack i started getting bad stomach cramps. i attributed it to my body getting adjusted to foreign food, but the cramps, while less painful, are still rather persistent and range from my stomach to lower-left side. i have also been experiencing weird hunger, in which i have the desire to eat but everything seems unappetizing or makes me nauseous.

i started freaking out, thinking i had some strange std symptom, but i have no other symptoms and have been in a monogamous relationship for the past 9 months. and while i have yet to take a pregnancy test, i have been on birth control for the past 4 years (so my uterus is something of a barren wasteland) and i use condoms with my boyfriend. i was freaking out a bit with these side cramps, wondering whether or not i should make a doctor's appointment. when taking orthotricyclinLo i had little to no side effects, and i have never gotten menstrual cramps before, so i hadn't thought that this discomfort could be from my pills. i was thinking of making a doctor's appointment, but after reading this blog am reconsidering, and might just wait out another month or so.

has anyone else had a similar cramping/discomfort experience, and did it ever subside?

thanks!
