Pregnancy Info HOME

HI ! I think I have conceived. I just had one intercourse in the ovulation days but I had implantation cramping for a few days after that. I am having backache and weakness off and on. There are still a few days to go before the start of my periods date. I read reviews that a lot of pregnancy tests are usually not accurate and give false negatives. Please tell me which pregnancy test kit is best and accurate to detect an early pregnancy.
