Pfizer infertility

34 replies

Newmama93 · 17/09/2021 11:40

Hi all,

Has anyone gotten pregnant after being double vaxxed with Pfizer? Sorry if this seems silly but a few of my friends are struggling and also had irregular periods since being double dosed so I wanted to ease their minds. I’m not TTC yet but now have irregular periods!

Thanks for sharing x

Hey.

Had my second jab on the 4th September and got my positive test on the 26th sept 😊 I'm now coming up to 7 weeks pregnant

Nailingnow · 09/10/2021 07:14

I find this thread comforting - thank you for starting!

JackieGoodmanLovelySquirrel4 · 09/10/2021 02:40

Agreed!

CaramelWaferAndTea · 09/10/2021 02:04

Fully jabbed by March conceived on second cycle trying in July. DH also fully jabbed. Six pregnant friends conceived after one or both vaccines

@Tippexy I don't think it's fair to say that this is a scaremongering thread. It is FACT that thousands of women have reported irregular periods after receiving the Pfizer vaccine. What is unknown, however, is why this is happening. It is being investigated and 'so far' there is no link to infertility.
Women who have irregular periods since receiving Pfizer (I know of 3 friends that have experienced this) are of course going to be concerned and have a right to express their concerns, as does the lady who started this thread

I got Pregnant one month after my first pfizer jab. Dh had also has one jab at the time

nickie01 · 27/09/2021 06:27

I got my first shot during my TWW. Husband had both shots already, 6 weeks pregnant

Dollywilde · 19/09/2021 16:44

Unexpectedly pregnant after we were both double jabbed - DH was AZ, I was Pfizer. Took us nearly a year of ovulation targeted sex to get DD in 2019. This was a one shag wonder…

MadamMaltesers · 19/09/2021 16:42

i had the pfizer back in may and im yet to get pregnant, this is the longest its ever taken me to get pregnant. i have the exact same concerns tbh. my periods were irregular following the jab too. im hoping tjings will get back to working order soon though.

Thanks for sharing everyone!

People that say I’m fear mongering I’m definitely NOT, I’m asking a question due to so much misinformation out there and a side effect of irregular periods I wanted some reassurance that people have gotten pregnant, I now have that so know that it’s all BS that it can cause infertility. Thanks again to the lovely women that shared x

Not Pfizer but very soon after my second Az jab after seven months of trying.

NigellasMicrowave · 17/09/2021 16:33

Yes - positive pregnancy test six days after my second Pfizer.

AllyCat31 · 17/09/2021 16:05

Can. CAN get pregnant 🤦‍♀️

AllyCat31 · 17/09/2021 16:02

Just to share my experience - first dose I didn’t ovulate and my cycle was really long. Second dose I had delayed ovulation but then got pregnant. Currently 6w3d. Have a friend who’s 20w and she was double jabbed too but earlier cause she’s nhs worker.

It’s not nice having your cycle messed up but it will go back to normal and you can’t still get pregnant! Try not to stress 🙂

Chad23 · 17/09/2021 16:00

I did - I came off cerazette in February due to irregular bleeding. I had my second vaccination in April and continued to have irregular periods. Conceived early July.

Bells3032 · 17/09/2021 15:29

@guac in both my friend and my case it seems our ovulation was delayed by about a week. in both cases we thought our next period was weird but turned out to be implantation bleeding. since all three were within a month couldn't tell you about irregular periods.

From my other friends some said they had one the following month but was back to normal after that (as you would expect with fevers etc)

guac · 17/09/2021 15:09

Of all those who got pregnant after being double jabbed, did any of them have irregular periods after the jab or did they continue as normal?

OrangeJuiceAndNoodles · 17/09/2021 14:47

Fully agree @IsabelHerna

It's never a bad thing to let people ask questions.

OrangeJuiceAndNoodles · 17/09/2021 14:45

I had pfizer and then got unexpectedly pregnant.

My periods were irregular afterwards but clearly, there was no ill effect. The opposite actually Grin

TheGrumpyGoat · 17/09/2021 14:45

@IsabelHerna

The only way to fight misinformation is with information from credible sources. When we don't know something, it's good to ask a question, so I would say to OP bravo for asking instead of fully trusting the misinformation and scaremongering out there.
This is true. Rather than calling to delete threads, it’s better to answer the OP with accurate information, which is then available for others to read.

Welshcake15 · 17/09/2021 14:19

Double jabbed (first one before becoming pregnant) and now 17 weeks along. I know of several people who are also pregnant after having been vaccinated. There's no known link between having the vaccine and fertility issues.

Missmonkeypenny · 17/09/2021 14:13

We needed IVF after 3.5 years of trying for DS, male factor infertility.

Fell pregnant a month after having my vaccine whilst still BF, having not had a period in over 2 years. We joke about the vaccine being the reason I got pregnant Grin

Hello everyone. These threads always draw many reports as posters are (quite reasonably) alert for misinformation. At the same time, many posters do ask questions here because they've had conflicting info from other sources and we think that's pretty understandable.

Misinformation and scaremongering helps no one and so we'll generally remove links to misinformation, or claims presented as fact but without a/a reliable source. As always, we'd advise consulting a medical professional if you have any questions or concerns. You can also take a look at the NHS website for more information.

Thanks.

PurpleDaisies · 17/09/2021 12:59

Not again. This has been asked over and over again by faux naive mostly first time posters.

There is no evidence the vaccines cause infertility. None.
