Yes — MomMed has a sensitivity of 25 mIU/ml and can detect pregnancy at 13 if HCG is above this threshold. Typical HCG at 13 is 60–200 mIU/ml. A faint line at 13 on MomMed is a meaningful result.
A faint line on a MomMed test at 13 DPO is a meaningful result. HCG at 13 DPO typically ranges from 60–200 mIU/ml — well above the 25 mIU/ml sensitivity of MomMed in most cases.
If you are seeing a faint line at 13 DPO on MomMed it is very likely a true positive, particularly if the line has pink colour and appeared within the 5 minute reading window. Retest in 48 hours with FMU and the line should be noticeably darker.
MomMed uses pink dye. A true positive line on MomMed at 13 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 13 DPO, typical HCG levels range from 60 to 200 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.
13 DPO is one day before most women with a regular cycle would expect their period. A positive at 13 DPO on any test is a reliable result. A negative at 13 DPO on a sensitive test makes pregnancy less likely though not impossible.
48 hours is the recommended retest window after a faint result at 13 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.
FMU is still recommended for the strongest possible line at 13 DPO.

Yes — a faint line at 13 DPO on MomMed with pink colour that appeared within the reading window is likely a true positive. Retest in 48 hours to confirm progression.
Yes. MomMed has a sensitivity of 25 mIU/ml. Typical HCG at 13 DPO ranges from 60–200 mIU/ml, so detection is possible in most pregnancies.
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 — FMU is still recommended for the strongest possible line at 13 DPO.
MomMed has a sensitivity of 25 mIU/ml — Other sensitive brands like FRER and Clearblue have similar or lower detection thresholds.
At 13 DPO, HCG typically ranges from 60–200 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.
