Your clinic's date takes priority

This is an estimate for information only — only about 1 in 20 babies arrive on their due date. Always confirm dates with your midwife or doctor.

Day by day after a day-5 transfer

Timings are typical patterns, not guarantees — implantation varies from person to person.

DayDateGestational ageWhat is typically happening
0DP5DTAug 102w 5dTransfer day. The blastocyst is placed in the uterus.
1DP5DTAug 112w 6dThe blastocyst begins to hatch out of its shell.
2DP5DTAug 123w 0dHatching continues and the embryo starts to attach to the uterine lining.
3DP5DTAug 133w 1dImplantation begins.
4DP5DTAug 143w 2dImplantation continues as the embryo burrows deeper.
5DP5DTAug 153w 3dImplantation is usually complete; hCG starts entering the bloodstream.
6DP5DTAug 163w 4dhCG is rising but is still too low for most home tests.
7DP5DTAug 173w 5dA very sensitive home test may pick something up. Results here are unreliable.
8DP5DTAug 183w 6dhCG is more detectable; faint lines are common but not conclusive.
9DP5DTAug 194w 0dMany clinics run the first beta hCG around now.
10DP5DTAug 204w 1dA home test is usually reliable by this point.
11DP5DTAug 214w 2dTypical latest day for a first beta hCG.
12DP5DTAug 224w 3dIf the first beta was positive, a repeat is usually 48 hours later.

Why the IVF wait is shorter than two weeks

In a natural cycle the two-week wait runs from ovulation to a missed period. After IVF the embryo is already three, five or six days old when it is transferred, so the clock is already part-way through. That is why a day-5 transfer is usually tested around nine days later rather than fourteen — and why a day-3 transfer waits about two days longer than a day-5 for the same result.

Reading the DPT vocabulary

Clinics and forums count in days past transfer: 7DP5DT is seven days after a day-5 transfer. Adding the embryo age gives the equivalent days past ovulation — 7DP5DT is roughly 12 days past ovulation — which is how the IVF timeline lines up with a natural cycle.

About early testing

Testing early is common and understandable, but before about 9DP5DT a negative means very little and a positive may still be trigger shot. If you do test early, plan in advance what you will do with an ambiguous result — that is usually harder than the test itself.

After a positive beta

Your clinic will normally repeat the beta 48 hours later. You can compare the two values with the hCG doubling calculator, and see your estimated due date with the IVF due date calculator.
