Don't know about this particular tablet, sorry. My general advice would be to grab anything you can get. I've always had horrible hormone problems and in the early 2000s embraced any HRT gratefully. Then a report wittered on about raised cancer risk and after 3 happy years it was withdrawn. 6 years of HELL ensued (lying in bed all day shaking, shivering and then drenching with sweats etc., don't even mention mood swings!) I am now 66 and still suffering symptoms (started aged 50).
I also had slight blood loss for a while, it can happen, my best guess is that your own hormones surge or something....not a medic. I should relax about it, see your GP and discuss it. :)
