My head is all over the place so hoping for some advice 
The first day of my last period was 20/01. Last week I did a cheap Tesco test and it was negative, 2 days later I did another one and it was a faint positive. Today I did 2 cheap Morrisons test and both were negative. I just did a clear blue test and it's positive!
I'm feeling so confused but hoping for anyone who has experienced similar?
