BBT not matching other signs of ovulation?

Hi ladies!

I started monitoring my BBT for the first time while TTC and told myself it was more of an experiment but already got too invested šŸ™‰
I’ll admit as I was just playing around with it I haven’t taken it the exact time everyday but I have tried to make sure I have atleast 3hrs sleep and there is only an hour or so difference in times, not sure if this does make a massive difference? I also didn’t take my temp on CD 12 so again that may have messed it up šŸ™ˆ

However, I had lots of EWCM from CD 8-10 which did seem a little early but I do normally ovulate between CD 11-13 so not completely out of range. Had been monitoring my cervix too which was high and soft during these days. My temp dropped on CD 11 which research said temp drops 24hrs before ovulation so that all seemed to fit. I’ve taken my temperature this morning and don’t quite understand it and it’s now moved my ovulation date to CD 14. My CM was a lot less and cervix lower and firmer. I’ll attach the graph for you to see!

I guess what’s done is done and I knew it tells you about ovulation after the event. I actually started monitoring more for the end of my cycle as I wanted to see if temps stayed up or dropped in relation to pregnancy instead of taking loads of tests. Just this shift of ovulation means we did DTD CD 13 but not really since. Just hate the feeling of maybe missing your fertile window 😩 Our schedule was much better for when I thought I’d ovulated CD 12

Thank you x

I was having exactly this issue, we were trying for 7 months. I was ovulating later than my egg white mucus. The month I conceived I took Asda cough medicine, this specific one has an ingredient in it that like generally makes you have more secretions. That month I got egg white for longer and it covered my ovulation and I conceived. Hope you get your positive soon!

Your chart looks good, does look like you might have ovulated between CD 12 & 13. It only takes one sperm so don’t stress to much about not dtd too much, I only managed to dtd O-1 and got my bfp, keep temping as long it stays high you still have a chance!

@flyinghen
Thats really interesting thanks so much for sharing! It never occurred to me my EWCM might be happening too early for ovulation.

And thank you so much! I have heard about people taking cough medicine but only seemed to hear about the American version so the Asda version is super helpful I’ll definitely go and get some if this cycle isn’t successful!
Thank you again x

@Henski

Thank you so much! As I’m so new to BBT charting I am a bit cluelessšŸ™ˆ
Really appreciate your input and hope I did ovulate between CD 12-13šŸ¤žšŸ»

But that’s so good to know, we’ve definitely DTD around the time and as you say only takes one so hopefully this is my lucky cycle. Will continue to temp and hope it stays up!

Thank you again x

So it usually takes three consecutive high temps for it to then say you ovulated. So I think it’s say you ovulated around day 14. Saying that though one time I used opk and bbt and the bbt actually took 36hrs to rise after ovulation, so if something like that happened to you it could have actually been on day 13 instead?

@Blue2020

Hi! Thank you so much for your input ā˜ŗļø I think you’re right and as I didn’t take my temp on CD 12 has probably thrown it a bit. I didn’t really know what I was doing but after the dip and rise I’ve got quite invested šŸ™ˆ
I’ve had a dip this morning which I’ve read is an estrogen surge which would fit with ovulating earlier x

Hey, I’m no expert, but I think you will have ovulated around CD 13? With your peak LH the day before and then your drop in BBT which signals ovulation. Good luck xx

If your sleep isn’t super regular maybe do LH strips too and see how they align with the other signs? For me EWCM had no relation to ovulation, and like another PP I give cough medicine credit for my eventual successful pregnancy!

Thank you...I have fertile friend aswell but that says something completely different. Now not sure if missing dtd on the 14th due to hospital appointment we will have done enough šŸ™„ ...this is the other chart that changed this morning xxx
