You poor thing. You really are having a crappy time with this. YOu must be absolutely exhausted and fed up.
The tonic is safe during pregnancy although you might not need to take it in addition to the pregnacare at the moment. However, you will need an iron supplement of some sort so it's good that you are getting it in some form. When is your next consultant/midwife/gp appointment and will they do a blood test to check your haemaglobin levels then? It might be worth pushing for this in the next week or so, especially if the bleeds continue, as you may need to go on a heavier dose of iron. If they suggest the ferrous sulfate or some similar tablet then you could always mention floradix as an alternative then. You CAN take too much iron but it's quite hard to do - you'd need to be ingesting vast amounts. Holland and Barrett sell it, as does Boots, etc. I got mine from a chemist and it might be worth having a chat with the pharmacy there as they'll be able to advise really well on iron levels, etc. And maybe give your GP/Midwife a call to discuss whether you should up your dose.
My bleeds started at 23 weeks but they didn't put me on iron supplments until around 30 weeks, by which time I was quite badly anaemic. As I've said before, the twin pregnancy doesn't help (you tend to always end up slightly anaemic with these as you require double the volume of blood) but the bleeding really pushed my levels down. So at around 23 weeks, although I was on a pregnancy vitamin and mineral supplement (similar to pregnacare - just a different brand) I also started taking the floradix. I generally took it every other day or so as I still had the iron supplement in my standard pregnancy vitamins.
However, by the end they had me on giant ferrous sulfate iron tablets and I was swigging from the floradix as if it was going out of fashion and I still ended up badly anaemic (should have had a transfusion after birth but they 'forgot', but that's a whole other story....) so I wish I'd started on the iron supplements earlier.
Are you getting help with these bleeds? Are you going to hospital when they are happening or are you calling the hospital? If you arent' it might be worth doing so as I think it's important that the regularity and levels of bleeding find their way onto your notes so that they have a picture of what is really happening. I jotted down every time one happened (time, date, duration of bleed, 'amount' of blood - the latter was always a bit vague, as it's quite hard to measure) which even now makes quite astonishing reading as I'd no idea I'd had so many (lots of small ones that I never bothered telling the doctors about).
I really feel for you - I know how upsetting and exhausting it is and what a shadow it can cast. The second half of my pregnancy was spent in a state of fear and anticipation, which seemed like such a loss and waste and not how I imagined my lovely pregnancy would be.
