Ok so I'm currently 4 days late from my period...I've had really light cramping for the last week or so that comes and goes after like 2 min. My nipples are very sensitive and my boobs are sore. Every time I think I'm going to start my period I don't. Usually I have really bad cramps right before my period and this time I haven't had hardly any...just very light cramps and then they go away...do you think I might be able to test???
