hiya I'm a month late on my periods and been having symptoms like back pain tummy pain headaches feeling sick and being tired now I've had a light pink discharge when I wipe.. what does this mean? I already have a one and a half year old and all the pregnancy tests with him came up positive but with this I've took 4 and they've all came up negative :/ I don't know what to think, am I gonna come on my periods or not? my last depo was September with finished in decemeber, I had a long two week period that stopped just before Christmas and has had nothing since? can someone help??
