Help anyone

I’ve got two faint positives on different days, another day a negative, went to the doctor for something unrelated to pregnancy and because I needed medication they doubled checked and again the doctor saw a faint line. Told me to test in a week because it might be to early.

Well I couldn’t help myself so tested this morning and I could swear I saw a line that disappeared and in the end negative.

Don’t know what to think.

I got off of birth control recently so I’m not even sure when af is due and don’t really have any symptoms for it.
