Does anyone else use there heart rate monitor on there Fitbit to monitor when they have ovulated? Saw a post on here recently where someone was but can't find it now. Been reading up on it thought it would be interesting to see how many of you guys did?

Sorry meant to add that the below was in the cycle I got my Bfp. The cycle before my RHR started to drop day 1 of AF and then hit its lowest point a few days into AF. That seems to be a common trend. Then it gradually works it's way back up in the second half of your cycle.

@dulwichdays Mine rose slightly before ovulation too, then continued to rise for a couple of days after, dipped a little and then climbed and climbed (the odd up/down fluctuation but the general trend was up). I'm still not sure it's that accurate as a way of telling you're pregnant if you're in the tww as I think a lot of woman have their heartrate stay up until the day of AF anyway, but certainly if you had no idea and then thought, "hey I've missed my period" and then looked at your heart-rate data, you'd possibly know then something was up before taking a test. What I didn't get was a sharp implantation spike like some get, it was a more gradual drop of around 2bpm and then a rise again over a few days.

I'm 3 weeks past ovulation now and my heartrate has increased a lot in the past week (as has my time spent in the fat burning zone which is another clue!).

Yeah since about 13 weeks old they've been great at night, I pray it lasts because a good night sleep is the only thing that get me through the days 😂 xx

ndo4000 · 19/04/2018 21:38

Omg @twincessesmummy !!! 9 hours?!?!? I get about 5 hours!!!

Tonight was a breakthrough - I actually put her to bed at bedtime! I've spent every evening before this carrying her around in a sling!!! Grin

twincessesmummy · 19/04/2018 20:02

That's what I remember ndo! Although it's all a bit fuzzy now!
Mine has also dropped right down again, used to get so high when I was pregnant with the twins! I still wear my Fitbit I like seeing how much sleep I get lol! The girls are sleeping well at the moment (touch Wood) I got 9 hours last night hooray!!

ndo4000 · 19/04/2018 08:06

@dulwichdays yes, I think that was the general trend. HR would rise after ovulation until just before AF and then plummet. If pg, then it would go on rising b4 staying high during pregnancy.

Interestingly, after my LO arrived the next day my HR bottomed out at about 45bpm! It took a couple of weeks for it to get back to normal. Weird!

Congratulations everyone! I’ve been trying to read back through the thread to see what the general theme was with the resting heart rate chart but struggling to get a clear answer. Mine seems to be lowest at AF, rising through to ovulation with a slight dip afterwards and then rising prior to expected AF again?! Does that sound about right?

Tentativesteps133 · 19/04/2018 02:07

I was also in the original chat. Awake feeding my 4 month old at the moment. Don’t wear my Fitbit anymore as don’t want to see how little sleep I’m clocking lol!

twincessesmummy · 18/04/2018 20:12

SpongeBobGrannyPants · 16/04/2018 22:37

Oh wow, you had twins!! Congratulations on your Fitbit babies! @twincessesmummy and @ndo4000

twincessesmummy · 15/04/2018 22:07

I started this thread, crazy! I'm laid in bed looking at my 3.5 month old twin girls sleeping! Being obsessed with my HR Chart feels like a lifetime ago. Good luck to you all still trying, and congrats to the rest :) x

ndo4000 · 15/04/2018 22:05

I was in the original chat! Am sitting here with my little girl sleeping on my lap! She was born in January!

Congratulations @SpongeBobGrannyPants & @CRZ1988 for your bfps!

SpongeBobGrannyPants · 15/04/2018 21:54

Congrats @CRZ1988
Yay for the Fitbit babies!

CRZ1988 · 15/04/2018 20:40

@SpongeBobGrannyPants I got my bfp in January and am due October! Congratulations on your bfp! X

SpongeBobGrannyPants · 13/04/2018 16:56

I know this is an ancient thread but I’ve been reading this with interest and noticed a similar trend with my own heartrate the past cycle. Got a BFP this week! How long before Fitbit start marketing the wristbands as a fertility monitor I wonder!?

I think most of the ladies on here who got BFPs will have had their babies now. Hope all is well and thanks for sharing all this info a year or so ago!!

CRZ1988 · 17/12/2017 12:16

I've been monitoring my rhr along with using OPKs. I had a strong positive on the one I did yesterday but my rhr still hasn't dropped. When I started using my Fitbit back in November it was around 51 and it's climbed to 63 and started to drop to 61 today. Would that indicate that ovulation is imminent?

This is my chart as of this morning.

CRZ1988 · 14/12/2017 11:58

Is anybody still watching this thread?

gerriberry · 28/11/2017 06:52

12dpo, heart rate still high at 71bpm but BFN this morning on a First Response so I guess I’m out!! Don’t know what’s going on with my rhr though!!

gerriberry · 27/11/2017 13:44

I know @juneybean and I have had left pelvic pain today and yesterday. Ended up in the chemist today and despite what I said bought a first response so going to test in the morning!!!
