One thing to take into consideration is that it takes 6-9 days for an egg to implant. For me this is my first month TTC with #2. I believe ovulation was 5 days ago. Today I got twinges of slight pain down low. I had my fingers crossed. I'm seeing all these signs and then looking back into my previous months charts I had mittelschmerz pain around this same time (I get it intermittently for a few days every month). I knew this but since we went from preventing to now actively trying, for some reason I completely forgot and now see everything as "THAT COULD BE PREGNANCY!". Even though I've had the same symptoms for months since getting off BC, suddenly now that I'm TTC I ignore that fact. I have no advice other than to say wait until at least 4 days before your period is due. After all the research I've done it seems nearly impossible to get a positive before then, and even so it could take a few days after it's due to get a positive, though there's always the exception to the rule. For me my last pregnancy I took a test the day before and it was negative. 24 hours later it was a faint positive and had a yeast infection and back pain spring up an hour before the positive test. Good luck and don't stress out too much (easier said than done). Stress can delay ovulation and lead to a late period.
