Preggy or stress??

Good day! Im 20 days delay but still my PT is negatve. Nag pa check up ako last sat for my ob. My ob told me to wait until oct 27 to confirm kung preggy or stress lang ako. The weird thing lng kasi, alm mo ung feeling na my lumalabas sau na prng mens pero watery lng siya? Hnd ko tuly alm kng discharge lng siya or mag kakarun ako. Now im using pads pero wala nmn na labas. My little brownish watery. Little paranoid kng ano toh. Any opinions momies? ❤️❤️ thank u for the responses.
