Bleeding Whilst On Femoston Conti....

Hi, I'm new to this community and am looking for some advice please. I will give you a brief history, had to have ovaries and tubes removed end of November 2017. Anyway, pretty much instantly after op had the full on hot flushes which were awful but was determined to go without hrt. However, my existence was horrible, no sex life and just felt rubbish, by the way I am only 46. The hot flushes had such an impact on my life, found it hard to function and I almost broke down. So, end of June last year, went to the doctors and he put me on Femoston Conti. Within 2-3 weeks the hot flushes had almost gone completely, amazing. Every month I got a touch of a bleed and was told I would as I still had a womb, there was a couple of times where there was nothing and other times a lot more. Now I seem to be constantly spotting, more so when I've had a bowel movement. Went to doctor and he told me to stop the conti for 7 days and then to start the Femoston sequi. I am on day 3 of stopping and am still spotting but now got some cramping. Is this normal, did anyone else bleed non stop on the conti and whats the sequi version like? I'm panicking slightly due to bleeding but with the current situation am wondering whether it is important enough to get referred to gynae.....?
