No AF...Not Pregnant

Ashley

32 years old. Off of BC since May 1. TTC. Last period was 8/25-8/29. Never had any issues with AF prior. Long time BC user...pill, then IUD, then pill again.

I was supposed to get AF last week. Didn't, so I took a pregnancy test. Negative.

Still haven't gotten AF. Took another test this AM and still negative.

Should I be calling my MD?????
