The first day of my last period was June 17th I had unprotected sex June 28, 29th & July 1st. Ive taking hpt but all come back negative. I find myself craving foods then when I eat I find myself not wanting it anymore. Ive been having period cramps but no period. If I stand up for more than 2 minutes I get light headed. And I've been making more trips to the bathroom lately. I get headaches right before bedtime and it makes me want to throw up, but I hate throwing up. I went and got tested for a std and it came back negative. I just have a yeast infection. Should I go to my doctor and ask for a pregnancy test??
