I'm currently day 41 of my cycle and there's no sign of anything coming any time soon. I've a really tender chest and feel really nauseous atm but that's it. My period is of medium flow for day two then light the rest of the time. My cycle can range from 30-48 days. The longer it takes, the more anxious I feel. I've taken 8 pregnancy tests with different brands so I'm ruling that out as they were all negative. At times I have a really uncomfortable pressure and it almost feels like there's something in there! It can be really uncomfortable to sit. I'm regularly constipated and when I do finally go, there's a lot of sharp shooting pain through my whole abdomen. Does anyone know what this could be? Or suffer with anything similar? I'm 35 and this has been ongoing since having my IUD removed 18 months ago.
