I also get my periods 30 days apart, and always on time (the 17th of every month). Me and my hubby tried to have a baby and ttc on the 2nd and 3rd of october (which is when I would definitely be ovulating and be fertile). I was so anxious to find out if I am or not, that I took one test on the 5th of oct and another on the 11th. Both were negative of course, but then I took one on the 16th of october right before I went to bed, and it was negative again. I broke down into tears and then the next morning I got my period that lasted heavy 2-3 days and then it was light/spotting for the next 3 days. I didn't know what was going on, maybe a miscarriage or something, so I went to my obgyn and asked her if I could get a blood test done, just to be sure. But she refused, because I already had my period this month. I was a little dissapointed, because things weren't going the way I wanted them to. I wanted her to take the test and then call me the next day saying that I am pregnant. But, she just told me to "get it on" with my hubby that night and today and then every other day after that... And if I don't get my period by thanksgiving, then to come see her to take the blood test.
So wish me luck guys! I need all the baby dust I can get!
