Sorry I knew that was a bit confusing! That's what I meant, yes, there is no symptom that definitely means something until well after the point where a test will be accurate. All of the potential symptoms of being pregnant in the very, very early stages can also be PMT symptoms. So it can be fun to try to spot the symptoms but it can also do your head in needlessly!
If you are curious, there are at least two potential scenarios that can cause EWCM after ovulation without having to do with being pregnant. This is the science AFAIK:
An increase in oestrogen levels leads to EWCM (or whatever your most fertile cervical fluid is -- for some people it's more watery than egg white-y) and to ovulation.You have low oestrogen when you're on your period, it gets higher leading up to ovulation where it peaks, and drops off a bit, then it rises a bit but not as much, more to an intermediate level, before dropping right down again for your period to start. So it's possible to have EWCM from oestrogen rising after ovulation.
There's another possible explanation as well: After ovulation, a structure forms on the follicle where the egg came out called the corpus luteum. It releases progesterone for around 10 days. If pregnancy occurs, it keeps releasing progesterone. If pregnancy does not occur, it breaks down and the endometrial lining begins to shed, and the first thing to go is a bit watery and can seem like EWCM.
