ask: Can you spot bleed days before your actual period starts, or is the spotting considered the start?

By Anonymous

I am looking to get pregnant but am having trouble figuring out the actual start day of my last period. My periods are usually light on the first day, but sometimes I spot a few days before the actual flow begins. I'm just curious if the spotting is considered the first day to calculate ovulation from.

I also wondered about the real "Day 1." As this page was loading, I figured out a practical way to find out. It takes 3 steps to find out.

We know that the luteum corpus is formed as soon as ovulation has ocurred. Then the luteum corpus begins to produce progesterone and this causes the elevations in temperature. This luteal phase is constant and began exactly 14 days before the beginning of the period. The beginning of our period, Day 1, is when the luteum corpus has disintegrated and no longer making progesterone. The low progesterone levels cause our lower temperatures.

So the average temperatures of our follicular phase (before ovulation) should all be lower than the average temperatures in the luteal phase (after ovulation).

Step 1. Pick "Spotting Day 1" as the first day of your menstrual cycle and count 14 days before. That was the day of ovulation and the beginning of the luteal phase according to this sample of temperatures. So take the averages of those two time frames. Before ovulation (follicular phase) and after (luteal phase).

2. Now, ignore the days we spotted and pick "Heavy bleeding Day 1" as the first day of your menstrual cycle and count 14 days before. Again, take the averages of the temperatures before ovulation and after for this sample of temperatures.

3. The averages that show the biggest difference between the two phases is most likely the "real Day 1."

When I did this, my average temperatures were more different when I counted "Heavy Bleeding Day 1" as the first day of my cycle. So for me, my "True Day 1" began on the days my heavy bleeding began and not the spotting.

My Example:
A. "Spotting Day 1": Follicular Phase Average Temperatures 36.23, Luteal Phase Average Temperatures 36.41. The difference = 0.18.

B. "Heavy Bleeding Day 1": Follicular Phase Average Temperatures 36.17, Luteal Phase Average Temperatures 36.52. The difference = 0.35.

P.S. I had three months worth of data to work with.

I hope it helps!

thanks for the tips.
I cannot figure it out when is my ovulation date is.
Please help me on that, here is my story:
About the Period: should I count the first day of my Brown spotting, usually have 1-2 days of Brown spotting then heavy bleeding for 2 days(needs to change pads,2 pads a day) then Light and at the end brown spotting. From first day of spotting to the last day of spotting = 9-10 days.
Base on that My LMP past 3 months: 14-22 Nov,11-20Dec ,8-17Jan
When is my ovulation day exactly?
Is my cycle length 26-27 days or 28 days ? when is the best fertile days ?
Should I count my LMP first day of my heavy bleeding or first day of spotting?
I know that I need to add 14 from my first day of LMP and get the ovulation day but want to make sure I know the LMP right.
Thanks

I am very confused and in need of advice. I have very irregular periods and this month on the 25th day of my cycle I started spotting. Not too light but not enough to consider a period. I spotted for about 4 days when my period is only 2 days. I have had increase in vaginal discharge since then along with terrible acne mood swings light cramping and soreness in my breast. I tooka hot and it was negative. Any suggestions?

Hi Anon

If your test said you are not pregnant then this is most likely to be a very light period. I don't know where in your cycle you are now but you could be ovulating (vaginal discharge) or getting ready for your period again.

Best,

Susan

Hi Anon

It seems your period is extremely irregular, making conception a challenge.

Why did you have the D&C?

Hi Anon

I'm very sorry for you loss.

I think it's a good idea to see your doctor. Since you have been trying for over a year, you may need to help to regulate your cycle and/or make sure your fertility levels are in good order.

Please update us when you can!

Hi. I have a question. For about a 1 1/2 weeks I had some cramping, then this past thursday I started spotting some brownish like stuff. It lasted for about 3 days. I took a HPT on that Friday and it had a faint but postive result. Now it is Monday, and I just went to the bathroom and noticed I have started bleeding reddish blood. Could this mean that I am having an early miscarriage (if HPT was accurate and from our calculations I would only be about 3-4 weeks along), or is it possible to start spotting again. It's not heavy at all. I am having minor dull like cramping as well. I am a bit worried by this. My husband and I have been trying to get pregnant for a few years now. I have a doctors appt. schedule for the end of the week. Thank you in advance for any information ya'll could give me. =-)
