babybumpkit started at home. My wife and I went looking for answers to the questions these pages now cover — the ones you end up searching at two in the morning, when the appointment is days away and you want to know whether to worry tonight. What we found was mostly one of two things: tools so clinical they felt cold, or sites so stuffed with advertising that the answer was hard to reach. My family is the reason this exists, and the reason it stays free and quiet.
I am not a clinician, and nothing here is written as though I were. Every article is researched against ACOG, the NHS and the Mayo Clinic, every medical claim links to the source it came from, and anything I could not source properly simply did not get written. Where the guidance genuinely disagrees, the pages say so rather than picking the tidier answer.
That means this site can tell you what the evidence says and what the usual advice is. It cannot tell you about your pregnancy, and it is not meant to replace the person looking after you. If something here contradicts your midwife or doctor, believe them — and please tell me, because it means a page needs fixing.
How a page here gets written
Every article starts from the primary guidance rather than from other pregnancy sites — ACOG committee opinions and practice bulletins, NHS guidance, and the Mayo Clinic — and the sources are listed at the foot of the page so you can check them rather than take my word for it. The date at the top of an article is the last time the page itself was gone over, not the date of the guidance behind it.
Where the evidence is genuinely unsettled, or where UK and US practice differ, the pages say so instead of picking whichever answer reads more cleanly. A number with a range around it is more use to you than a number without one.
What this site will not do
It will not tell you what is happening in your pregnancy, diagnose anything, or stand in for the person looking after you. The calculators work from dates and averages, and an average is a poor description of any particular pregnancy. Anything that needs examining needs someone who can examine you.
It also will not pretend to a qualification. There is no clinician on the masthead, so there is no “medically reviewed by” badge on these pages — adding one would make the site look more authoritative and be untrue, and on this subject that trade is not worth making. The full medical disclaimer sets out the rest.
Corrections
If something here is wrong, out of date, or contradicts what your midwife or doctor has told you, I would genuinely like to know — email hello@babybumpkit.com. Corrections to medical claims get made first and the page's updated date moves when they do. Believe your provider over this site in the meantime; they know things about you that a web page cannot.
