target brand test: evap or faint pos?

Angela
I am 10 months postpartum, my first cycle was 9/8. I somehow haven't had a cycle but did ovulate on or around 10/11. I had a urine preg test done by the dr on 10/11 and was negative. Lately I been so emotional, grumpy, slightly cranky, the hangover feeling with headache.. And today I almost threw up randomly. 
I used this up & Up brand "early result test" and before the 2 minutes was up I could swear I seen a line.. and this isn't FMU. I also have been testing with the Wondro (or however you spell them) tests and they been negative, but I do look back at them and think I see a line .
