Hi should I be worried I gave birth in September and combination fed for 6 weeks. Then had a heavy bleed when I stopped. I haven’t had any bleeding since. The baby is donor egg ivf and I’m 41 and it was ivf no 7 so lots of drugs over the years as well as progesterone injections and pessaries till 14 weeks of pregnancy. Should I be worried that my period hasn’t returned? I have a doctors appointment in a couple of weeks so might mention it. But thought I would ask when other people Xx
