Hi there, I only have one ovary so been very stressed about falling pregnant. My normal period is very heavy the first few days and i get heavy cramps and it lasts for about 5 to 6 days, this time it was just dark blood and was very little I only had to put a bit of tissue there to keep clean but it only lasted two and a half days. I did a preganancy test three days later and it came up negative. Can i possibily be pregnant and when should i try a test again? Im praying i am its so depressing seeing your test come up negative.
