IVF question

[Kitkat369]

Hi all, just wondered how it works when undergoing ivf in terms of cycle days. If starting ivf and from day one of cycle you take drugs/injections what day do you tend to have eggs collected? As I understand it the clinic would control my cycle once I’m down regged, I just don’t understand how ovulating v egg collection works, would it be same cycle day or be bought fwd? Would love to get your experience on ivf from cycle day1 to day when collected.

Depends on your protocol.

Have you been to an information session from a clinic?

Like @Kate states it depends on your protocol, your usual cycle and how you respond but to give you a clue here's my IVF cycle timeline on long protocol when my usual monthly cycle is 28-30 days.
Start down regging on day 21, 18th May
Started stims 9th June
Egg Collection 23rd June
Egg Transfer 28th June
OTD is the 11th July
I was a slow responder to stims so ended up stimming for nearly 2 weeks but I think about 10 - 12 days is average.
Before I started down regging I had a baseline scan at the start of May, I then had a pre stim scan the week I started stimming and 3 scans during stimming to see how things were growing.

I haven’t had my info session yet and just want to get idea before jumping in. My dr suggested Endo scratch first before ivf. I was just curious how due dates calculated if it’s all manipulated by clinic.

I think it's calculated from your egg collection date I've looked at a calculator on line and should I get my BFP I'd be due around 16th March.

Short protocol is largely based on your cycle, so you stim during the first half of your cycle, and have egg collection mid-cycle, around when you would ovulate. I can't remember what day EC happened with my other cycles but on my last one I responded quite quickly and ended up having EC early, on about day 10 of my cycle.

For long protocol all bets off off. Downregging shuts down your cycle and they can leave it like that for as long as needed. My first nhs cycle was long protocol and they asked me to spend an extra week downregging to fit in with their clinic timing. I ended up quitting the cycle as the downregging drugs sent me loopy and I couldn't cope with another week. I then went private and all my cycles were short mild or natural.

You don't start stim injections on day 1 as they want your old lining to shed first. I've usually started on day 3-5ish. Then injected with until egg collection around 12 days later. It doesn't matter when you'd usually ovulate as the clinic will be scanning to see the growth. They get you to take a trigger injection when things look nearly ready and then egg collection is around 36 hours later - too much longer and you could ovulate and lose the eggs. The day of egg collection is the same day as they are fertilised and is considered ovulation day for calculating due dates. You go by this rather than first day of last period as is normally used for calculating due dates as your cycle has been manipulated.

It depends if you're short or long cycle. I was long cycle both times but first cycle I had a week longer of down the injections to fit in with the clinic over Christmas and new year so you can't predict it until your planning meeting - even then it can go haywire if you don't respond to the eggs correctly.

If you get a bfp minus two weeks form your egg collection date and that's the first day of your "last menstruated period" on usual calculators or for midwife booking etc. So if you get a bfp on your official test date your normally already roughly 4 weeks pregnant.

Thanks so much for this. I’ll reach out to my clinic for info meeting with nurse as to next steps. Very nervous
