I've been getting faint positives since 7dpo. I switched to a different brand at 11dpo and they seemed slightly darker but I don't know if that's just because I used pink dye instead of blue. I'm now 13dpo. Is it just WAY too early for me to be testing to know for sure or should I be worried I'm having a chemical? I had a MC July 29, levels reached zero on August 11 so I'm not sure when to expect my period. I think I ovulated aug 19 based on EWCM so guessing AF could be due tomorrow? Any advice would be appreciated!
