False positives don't really happen you are more likely to have a false negitive then a positive. The only way to tell how far along you are is an ultrasound or knowing the exact date you started your last period and start from there.
I had my last one the 8th of Nov and took test at home the 12 at the doc 13 and I'm do august 15 this will be my third but worried it may be twins tired all the time my hips hurt bad got cramps and get butterfly feelings in tummy at 6weeks really sick to stumack but got sick all the time with my last two but didn't have the other symptoms
No. If you took that many and they all came out positive then you are pregnant. And you can get a positive 5 days before your missed period so no its not too early.
