Good day, maybe the question is silly, but I want to get some advice out of it) Three days ago I inserted a spiral, my cycle is very unstable on gvw, so the doctor said to do tests and if/we install them immediately, I came and did two tests, 10 mm and 25 mm, there's not even a hint of the second one, everything was installed well, after two days, there was one test in the bag, I'm generally fond of doing them ?‍♀️I do them on Abum and then a barely noticeable second spot appears, I run to the pharmacy and redo with another manufacturer, again two, this evening I'm doing two more, the next day
