My period this month is really strange, it came bang on time and felt like normal but it's really watery. The blood is bright red but looks almost like it's been mixed with water and thinned down. I'm leaking out of mooncup despite it not being full (mooncup has NEVER leaked for me before) and am soaking a pad as well, the blood is red on the pad but then kind of spreads out to leave a watermark. Every now and then I feel a gush and more comes out.
My last few periods have been fairly light and the blood has been mainly in clots-this month there have been no clots so far (day 3).
Any idea why this could be? Is it normal? (haven't had that many periods over the past few years so can't really remember how they used to be)
