Spotting

On Monday I woke up to some spotting. It wasn’t a lot, and I didn’t need a panty liner. It was bright red. Each day this week, there has been spotting. At least two or three times that I use the bathroom per day I see something (usually light pink) but only on the tissue. Today there wasn’t any spotting when wiping, but I did notice what appeared to be a clot (pinkish in color with like white on the outside) when the toilet flushed. Could this be the start of a miscarriage? I am 7 weeks today.
