To ask if pregnancy tests work in later pregnancy

[Mousecheese]

I was wondering if anyone can help. My period is three weeks late. I have done multiple tests since my missed period which have all been negative so I am not pregnant from this cycle. However, the strange thing is that for the last 6 weeks or so I have felt tiny flutters like baby kicks but just put it down to wind or something even though I have only ever felt the same feeling in pregnancy. Tonight the 'kicks' were really big and I looked at my stomach and it was moving just like when I was pregnant.

I know you hear about people not realising they are pregnant til later on but just wondering if pregnancy tests stop working after a certain time in pregnancy or would I get a positive result the whole way through?

A hormone pregnancy test detects the hormone HCG and your levels of this drop after the first trimester when the placenta takes over. So yes it is possible that you’d get a negative test when further along in pregnancy. Can you ask your doctor to do a blood test?

Phone GP in the morning and request a blood test!

Pregnancy tests are VERY sensitive and will continue to be positive throughout a pregnancy, even for a little while after a pregnancy ends.

Weeks from LMP Serum hCG Range
3 – 4 9 – 130
4 – 5 75 – 2600
5 – 6 850 – 20,800
6 – 7 4,000 – 100,200
7 – 12 11,500 – 289,000
12 – 16 18,300 – 137,000
16 – 29 1,400 – 54,300
29 – 41 940 – 60,000

Yes, I actually tried this once. When heavily pregnant the test came back negative.

Good luck OP, hope you get the result you want.
