Good morning, I have been taking Vibin tablets for 10 months - always at the same time, I have never vomited or stomach problems, I have never missed any tablet. Each time I got bleeding on 3 tablets of placebo and it was completely normal. A month ago, however, my period was scanty and began on the 4th day - it was a light, pink-brown spotting, only on the 6th day it was normal for a while, but then again practically nothing. I thought it was probably due to stress (relationship problems, session, etc.). This month (also stressful, although a little less than the previous one) unfortunately once again - the period began on my 4th day, again it is very stingy and this time completely brown, with blood clots. Despite the fact that it is very stingy, I feel pain as usual (and the period in my case has always been painful, so it seems to me that nothing has changed here). My question is - should I go to the doctor? Could this mean pregnancy?
