History:
I'm on Gildess/Microgestrin, as a side note. About three weeks ago, I thought I had a YI, so I decided to go to the doctor. She did a swab for any other infections, but said it looked like a YI and prescribed the YI pill-thing. That was a Friday. That next Monday I got a call about my swab results and they said I had BV, which is whatever, and that they prescribed me Flagyl. I filled the prescription and went about my business. No sex for a week, due to the antibiotic, and everything was feeling better after the seven days.
Fast forward:
I had sex after being off the antibiotics, but only waited two days, which as I now know isn't long enough to wait after taking antibiotics on your BC. The end of my pack fell on June 6th (of the 28 day pack), which was this past Monday, and I was supposed to start my period on the 8th/9th. It didn't come. I waited until Saturday, just to be sure it wasn't going to spring up on me a little late, and it never came. I took a pregnancy test and it was negative. I guess my questions are:
1. Was it too early to take a pregnancy test and expect accurate results?
2. Could the antibiotic have affected my cycle?
3. How long are you really supposed to wait to have sex after being on antibiotics with BC?
I'm just freaking out, I'm hoping. :(

Loestrin is one, and Microgestin is a generic for it. A single missed bleed is generally not cause for alarm.
3. There are only a couple of antibiotics that have been proven to affect HBC, in the Rifampicin family. These are hardcore abx used to treat things like tuberculosis. You do NOT need backup for most normal antibiotics (like Flagyl). However, IF your protection was compromised, seven days of active pills will get you protected again.
