My boyfriend and I broke up about 5 weeks ago. Things have been pretty hectic and I don't recall having a period since then- although I am forgetful and don't usually pay much attention to it so I could have had one and not registered it really. I have the mirena coil so had no concerns about being pregnant. I'm usually very regular with my periods and I'm now 4 days late. My boobs have been beyond painful for around a week, they feel very sensitive- not uncommon when I'm due on but it's significantly worse than usual. I've been crying on and off for around 2 days for no reason at all which is unlike me. Yesterday I thought my period had started as there was a small amount of blood when I wiped but it was more like a few drops and nothing more since. I took a test today expecting it to be nothing but just to put my mind at ease. I don't know if I'm seeing things but there is a very very faint line which concerned me slightly. Should I be worried?
