Hang in there. I went through a similar situation. I’m usually always regular…I had a normal cycle in January, no period in February, I got it again on March 1 but it only lasted for 2 days. I’ve been taking pregnancy tests since late March. All were negative. I even went to the hospital on 4/2 they did an ultrasound, a blood test, and a urine test…all were negative. Now, on May 25th since I still didn’t receive a period, my GYN had me do a ultrasound to look for possible fibroids or cysts as the cause of the problem. I found out on that day that I was 7 weeks 6 days pregnant!! It’s a crazy story, but it’s true…and even though I had my ultrasound pics, I still felt like I had to take another HPT for more proof..and the hpt came out positive. I’d suggest that you keep testing every couple of days. And better yet, go to the doctor or free clinic in your area and get a blood test and/or pelvic exam. I wish you the best…let us know how everything turns out.:)
