Alright guys, this is my first post here. I have no idea where else to turn to.

This past Sunday I should have started my period, and I didn't. I'm on Trilinyah birth control. However, near the end of last month I was on a ten day round of antibiotics for bronchitis. Me and my boyfriend waited the "appropriate" time before having unprotected sex again. It's been about 3 1/2-4 weeks.

I have taken two Clearblue tests which have both been negative, however I'm still having some major symptoms. Sore breasts, nausea and heartburn with anything I eat (I mean anything), fatigue, and some moodiness. I'm having back pain, but not in the area I'm used to.
