If u are very sure that the egg is released at around day 15, then it is a bit early to check bingo today. However, you have m symptoms. Maybe u go see doctor tomorrow la, at least he or she can give you better explanation.
Thx very much ah... I'm thinking to see a dr, tmr if I still see 流啡/血 tonite and tmr.... If I dun see it, then I'll wait a few more days and check cb digital again (since today is really a bit early to check bingo)...
