Chances are you will not have your regular period during chemo treatment. Worry about it if and when that bit happens.
The bleeding is a worry from the colon but if its just on the paper and a bit in the stool that's probably not grounds for ceasing chemo. You should have a blood test a few days before the next scheduled dose and things will be a bit clearer then what's going on and if your body is good to go for another dose.
The heart rate is a worry and it scared the hell outa me. Often I wanted to ring the ambos but seemed to muddle though and get over it by myself. My oncologist just looked at me like I was lying when I said for 12 hours my heart didn't have a rhythm, it was all over the place yet I was able to make it up the hall to the toilet under my own speed. I figured it out myself that it was my body in shock and for some unknown reason for me, taking Targin pain meds worked and my heart would settle straight away. The doctor could not explain this but was happy it worked. I only needed to take meds for a day or three, just to get over the initial nasties. Dr's still haven't bothered to do any heart checks so I figure I must be ok. I'm not dead yet lol.
See how you go the next week or so and perhaps have another oncology appointment just before any scheduled next dose. Blood tests may say you are good or you need at least another week to get over things. Three weekly is standard but there's nothing to say you can't have it 4 weekly instead. Perhaps the oncologist feels one dose was enough? I know that first one is a doozy so it could be enough.
Doses 2 and 3 were bad for me. My oesophagus went weird and I had terrible burning, reflux and bloat which made breathing difficult. I ate very little after dose 4 and that seemed to fix me up. Extra meds was just too much for me and I got though just taking it easy.
