8 DPO is early for MomMed to detect pregnancy. MomMed has a sensitivity of 25 mIU/ml and typical HCG at 8 is only 0–15 mIU/ml. A negative at this stage does not rule out pregnancy — retest in 48 hours with FMU.
A faint line on a MomMed test at 8 DPO is very unlikely to be a true positive at this stage. 8 DPO is at the very beginning of the detection window and HCG levels are typically only 0–15 mIU/ml — often below the 25 mIU/ml detection threshold of MomMed.
If you are seeing something at 8 DPO it is more likely to be an indent line or evap line than a true positive. Save your tests and retest in 48 hours with FMU for a more reliable result.
MomMed uses pink dye. A true positive line on MomMed at 8 DPO will be pink in colour — even if very faint. The key things to look for are:
A true positive MomMed line is pink and appears within the reading window. Enhanced or inverted images may make the indent more visible — always check for colour before calling a result positive.
MomMed can occasionally produce evaporation lines. An evap line typically appears after the reading window and has no colour. If the line on your MomMed test appeared within 10 minutes and has pink colour it is more likely to be a true positive.
MomMed strips are popular in the TTC community and generally considered reliable. Evap lines are possible after the reading window. Indent lines can be visible on some tests. Results should be read within the stated window.
MomMed has a medium risk of indent lines.
An indent line is a colourless depression in the test strip where the test line would appear if positive. It is caused by the manufacturing process and is not a positive result. Key characteristics of an indent line on MomMed:
- Has no pink colour — appears grey or colourless - Is visible on the dry test strip even before dipping - May become more visible on inverted or enhanced photos - Does not indicate pregnancy
At 8 DPO, typical HCG levels range from 0 to 15 mIU/ml. This is a wide range because HCG levels vary significantly between women and between pregnancies.
MomMed has a detection threshold of 25 mIU/ml. This means:
The Mayo Clinic notes that HCG roughly doubles every 48 hours in early pregnancy. If you retest in 48 hours the line should be noticeably darker if HCG is rising as expected.
8 DPO is at the very beginning of the detection window. A small number of women who implanted early may get a faint positive at this stage. For most women HCG is not yet above the detection threshold.
48 hours is the recommended retest window after a faint result at 8 DPO. This is because HCG roughly doubles every 48 hours in early pregnancy — retesting after this interval gives the best chance of seeing a meaningful change in line darkness.
Always use FMU at 8 DPO. HCG levels are so low at this stage that diluted urine is very unlikely to produce a positive even if you are pregnant.

A faint line at 8 DPO on MomMed is very unlikely to be a true positive. Typical HCG at this stage is below MomMed's detection threshold. Retest in 48 hours with FMU.
8 DPO is early for MomMed. With a 25 mIU/ml threshold and typical HCG of 0–15 mIU/ml at this stage, a negative does not rule out pregnancy.
Evap lines on MomMed typically appear after the reading window, have no pink colour, and appear grey or colourless. MomMed has a medium risk of evaporation lines. A true positive MomMed line is pink and appears within the reading window. Enhanced or inverted images may make the indent more visible — always check for colour before calling a result positive.
An indent line on MomMed is colourless — it has no pink colour and appears grey. MomMed has a medium risk of indent lines. It is a depression in the test strip, not a positive result.
48 hours — Always use FMU at 8 DPO. HCG levels are so low at this stage that diluted urine is very unlikely to produce a positive even if you are pregnant.
MomMed has a sensitivity of 25 mIU/ml — Other sensitive brands like FRER and Clearblue have similar or lower detection thresholds.
At 8 DPO, HCG typically ranges from 0–15 mIU/ml. If you are on the lower end of this range or implanted later, your HCG may barely exceed MomMed's 25 mIU/ml threshold, producing a faint line. Retest in 48 hours — a rising HCG will produce a darker line.
