I don't know where to start. I'm NOT pregnant but I'm 21 days late on my period. I've had no spotting throughout and I feel fine, physically and mentally. I've had no mood swings or I haven't done anything out of the ordinary. But I have been strangly tired a lot in the past 3 weeks. I've also tried masturbating 2ce and every time I've cummed, my lower abdomen aches, I can't really explain the feeling, it's almost like a cramp? I've had a little feel of my abdomen and there is a VERY small abnormal lump on the left side that hurts when I put pressure on it. My breast have also become bigger and they did start hurting around 3 weeks ago but they've been fine for a couple of days. I don't know if this is relevant but my bowl movement have definitely not been very good - I actually have around 2-3 poos a week but I don't feel like I need to go inbetween... I haven't changed my diet, increased/decreased my exercise regime etc so I have no idea what's going on there. I've also been experiencing 'shooting' pains in my left breast which is absolutely unbarably excruciating! And also on my right side (my waist) I hope someone can help me because I'm getting fed up of waiting for a period
