Faint positive but not pregnant on digital

[Mummyto1B]

So... I'm after some advice. I am 8 days late for my period and have been trying for another baby. I was doing pregnancy tests last week with all negative results. Monday j got a positive on the clear blue, a very faint line after 2 mins. I did the test again first thing Tuesday and got another faint line for positive - pic attached. Today I did a clear blue digital to find out how far along I was and it said not pregnant 😞 I have cramp today and when k went to the toilet noticed very red blood when I wiped. I'm getting worried now can anyone offer any answers or advice?
On the clearblue digital I broke it apart to see the test strips - pic included

If your 8 days late and a digi is saying your not pregnant I would think your not pregnant sorry. I actually think that picture of the test is not a very strong positive-blue test dyes are notorious for the ink lessons and being difficult to read. If you were pregnant I think the cramps and bleeding will be the start of a chemical pregnancy miscarriage. Don't be disheartened, chemical pregnancies are very very common. Try again next month.

I did a sure sign one at lunch time which also had a faint pink line which reassured me until the cramping this afternoon. Strange.
