My period was a little over two weeks late, it came... Eventually. At least I think that's what it was. I had very light bleeding for about 4-5 days. Prior to his, I took 8 tests all came back neg. Now, the bleeding is gone. I'm having lower back aches, always tired, my nipples are itching, I get hot flashes, and sometimes I feel a bit nauseas but Ive only thrown up once. Any ideas?
