opinions?

i know i'm crazy and i know i have line eyes BUT, i've been feeling exactly like i did with my previous pregnancy all week! and yes i know it's early to have symptoms but with my last pregnancy i knew before my missed period because i had extreme nausea (which lasted the whole pregnancy😩) and i've been feeling the exact same now! i took a test yesterday and got a faint positive, visible and within the timeframe, then took one again this morning and got nothing! i'd usually put this down to a faulty test but due to the nausea i'm not so sure, the nausea has also eased off today☹️ could this have been a chemical pregnancy? i'll test again tomorrow but pretty sure i'm out... thank you in advance ladies💖
