So I’m currently waiting to get my next cycle which was due to come on aug. 11th but she didn’t show up. And now I’m having back pains in my lower back my nipples hurt a little bit but not too much and I had a little bright pink blood when I wiped myself off on July 31st. Yesterday and today I took a test and they were both negative. So should I wait to test again or am I just being paranoid?
