I know this sounds odd but I'm late on my period, about 3wks late and I've eventually woken up this morning with proper period cramps. I've been bloated for weeks but I've got IBS so been putting it down to that. However, sorry for too much info but it feels like it's not coming out properly and it's blocked! I feel like I should be having a heavy period as normal but I've just got a swollen sore tummy that feels like it going to explode! It's driving me mad I could cry! My husbands had a vasectomy before pregnancy is mentioned, I honestly don't think it's anything like that. Please help anyone?
