Pregnancy tests not getting darker

Hi me and my husband have been trying since September! We finally got a positive test on Friday the 10th and it was a little light but definitely there.

They got a little bit darker the following day but now i feel like the test is just as faint as day 1..

this will be my 5 pregnancy in order 1 ectopic

2 miscarriage 3 baby girl 1 4 miscarriage 5 baby girl 2.

I know I’m still fairly early that it would be considered a chemical pregnancy but it just sucks we have 3 girls (husband has one from a previous relationship) but we were hoping for our boy but i don’t think i can do this again it feels like my body is failing me. Does anyone have any insight or opinions?
