I tested 5 days after I missed my period - Negative
I tested 10 days after I missed my period - Negative
I tested 13 days after I missed my period - Faint positive.
I took myself down to the doctor who told me to do a urine sample using my first urine of the day, and bring it in tomorrow. So on the way home I bought a "Clear Blue Digital" two pack and tested. It came back "Positive 2-3 weeks", clear as day.
The next day I did my urine sample, dipped my second test in there and sent it off to the doctors. That test also came back positive.
A couple of days later I received my result from the doctor - Negative.
I took 4 more Home Pregnancy tests and each one came up as a very clear positive.
I am now 8-9weeks pregnant and my last period was on 15th February.
I hope this helps but, at the same time, doesn't give you any false hope =[. It's best to test in the morning.
Best advice I can give, if you're not, is to stop trying. Sounds silly but as soon as I stopped stressing and calculating and checking...I fell pregnant. Also take "Pregnacare - Trying to Conceive" prenatal vitamins. I fell pregnant within 3 months of taking these.
Good luck. x
