Hello everyone! I'm 27 yrs. old and my husband and I have been married a little over a year. About 10 days ago my Dr. put me on a antibiotic for a UTI. I'm on the pill and am usually very good about taking it when I should, but my Dr. said antibiotics can negate the pill's effectiveness. According to my ovulation calendar info, I was to ovulate around this past Wed and my husband and I had sex the Monday, Tuesday and Wednesday before that without backup birth control. I have felt "off" since Tuesday (which I actually blame on a head cold), but am now experiencing the following symptoms: gas, indigestion/heartburn, moderate to intense back pain, PMS-like cramping in my abdomen, light nausea that comes and goes (usually coming when I eat), had very loose BM Th (4 times) then no BM from Th. pm to Sun. am., headaches that come and go (in various spots in my head and in varying intensities). I also feel a little restless and as though I'm going to get my period any second.

Does anyone have any wisdom or insight as to whether I'm looking way too far into this? Or, has anyone had something similar happen and ended up with a positive pregnancy test? Thanks!
