When I took a pregnancy test and April night when I took a pregnancy test and April night the first clear blue came back positive all the rest of the negative I've never had a home pregnancy test actually show up positive I would have only been about a week pregnant then I got blood work done and it was negative but then I found out it takes to weeks after ovulation to even be able to show I am really tired bloated pelvic pain hip pain abdomen pain very sore nipples headaches been eating more really hope that I'm pregnant go to the OBGYN on the 21st of this may hopefully get a sonogram to see why I'm having pains on my left side hope it's not ectopic pregnancy
