Looking for advice

I am now 12 days late have taken 3 tests from 3-11 days late all clearly showing negative or not pregnant but I can’t shake this feeling the past few days at night of feeling really sick and sore stomach tonight is the worst I feel I may actually be sick soon 🙈

Don’t seem to have other symptoms not sore boobs or anything but some really light discharge like clear tonight?

Any advice or support greatly appreciated 😞
