BBT CHART - HELP NEEDED!

[Leanneosaurus]

Hi

Is there anyone that has an understanding of BBT charting that can help me understand it?

I'm currently going through a second miscarriage, the first on 18th September last year at exactly 6 weeks and this one on Thursday 28th April at exactly 9 weeks. The reason I'm asking about BBT charting is because the first time I got pregnant I hadn't charted but I know I did the deed on cycle day 18. I charted part of my cycle in January, the month before I got pregnant this time (I didn't record it) and there was a distinct drop in temp on cycle day 18. I got pregnant this time in February and I did record my chart but only from day 9 of my cycle (I've attached it to this post though it's not the clearest of pics) and once again there is a clear drop in temp on cycle day 18 and that's the day I did the deed again. I didn't try to get pregnant in January but both times I've done the deed on cycle day 18 is the day I've become pregnant.

Can I assume cycle day 18 is the day I ovulate? I have a 31 day cycle.

The reason I'm asking about BBT charting is because I'm led to believe that if you're pregnant then after ovulation the temp stays up and although I only have this one chart to go by, my temp was up and down after assumed ovulation and I just wanted to know if anyone has an idea of what this could mean. Perhaps it shows something that I don't realise that could indicate why both pregnancies have failed, I don't even know if that's possible but I guess I'm just trying to find reasons as to why I lost both babies and if there's anything at all I can do in the future to stop it happening again and basically just have a clearer understanding of what the chart indicates, Luteal phase defects etc.

I know any advise given won't be medical advise, only opinions, my doctor has already asked me to pop in and see him, I'm lucky I have a great doctor, but I just want to know as much as I can to help me do better for my baby next time.

Thanks in advance for any opinions.

I'm not a bbt expert at all but it was my understanding that you need 3 temp rises above the cover line to demonstrate ovulation and it doesn't look like you've had that. Have you tried using fertility friend? It adds the cover line for you and also pin points ovulation.

I've had multiple miscarriages too and I'm starting to wonder if I might have a short LP but I'm afraid I don't know much about it to be able to advise.

Sorry, ignore me I didn't read your first post properly. I'm a bit confused though because I don't think day 18 looks like you ovulated but maybe the cover line isn't quite right. I'm sorry I'm not being very helpful.

I definitely ovulated because I was pregnant but perhaps I have low progesterone or something which is why there's not much if a rise

Yes, I think day 18 is right.

I've been charting for + 12 cycles, your temps all look fine.

You've been pregnant, which is a good sign that you're able to get pregnant.

If your cycles are 31 days and you ovulate around day 18 then that's 13 day LP, which is long enough for implantation to happen.

It's great your doctor is so helpful, but from my unmedical opinion I think your chart looks normal.

Thank you :)

I seem to get pregnant very easily, both times we only needed to do the deed once and it was on day 18. The only thing I can think at this stage without having tests is that low progesterone can be a problem. Luckily there's things we can do to correct that with healthy diet, prenatal's, increased vitamin C and zinc and progesterone cream. I'm taking the supplements but not yet the cream, I want to speak to my Doctor first before I do that as it may not even be the cause. Eating right and taking supplements can't do any harm though! I just don't know whether the cream can cause problems if not needed.
