Not all, obviously, but certainly some. For all my teen years, until I discovered the pill at 22 (hallelujah!), I had an extremely irregular cycle — anywhere from 18 to 42 days. So from day 14 on, I’d be miserable and anxious, never knowing when — no warning signs that I was ever able to discern. I woke up more than a few times with bloody panties, until I got smart and started wearing a pad to bed ‘just in case’.

I have always been told I am crazy or what not, and I did ovulate on the pill.. (strong buggers let me tell you) I got pregnant with twins on BC.

Not that I intended to get pregnant but there ya go.

My experience in pain, is not your knowledge to call me nuts.

I know when I ovulate and I always ovulate 2 times every month regardless if I have a period or not. I HATE IT! It hurts and it send me to bed for 3 to 4 hours a day because of it moving.

I was free from this pain for 18 months after a depo shot. That wasn’t good, hehe I don’t take the depo shot anymore.

I have had mittelschmerz as well, but at least in my case, it isn’t correlated very well with the onset of menstruation. At least, I can have it, and then it can be anywhere from the usual week, week and a half to six weeks before I’ll menstruate. What that means in fertility terms I don’t know, and I don’t want to find out. Left unmedicated, and celibate, I can sometimes go for three months without evincing any signs of ovulation or menstruation.

It’s all very well and good to postulate that human female fertility isn’t as cryptic as some people might think if you have menstrual cycles that are regular as clockwork and so on, but if you get anywhere out of that middle two quartiles of the normal distribution, all bets are off.

Hi, it’s because of mittelschmerz. And I know it’s always right on because I’m on the pill, so I can track my cycle clearly. But even when I was off the pill for a while I felt it. I think not every woman experiences this feeling (obviously).

Correct me if I’m wrong, but doesn’t being on the pill suppress ovulation?

i wear bras because i have breasts, not the other way around. and they started “protruding” well before i ever wore one.

What I meant was, without wearing bras, by the time we became adults our breasts would be all flat and flappy just like on ape females.

The human breast isn’t all full and round naturally. (Honestly – haven’t you ever seen the stereotypical naked tribeswoman on National Geographic?) And it certainly isn’t all full and round to allow for the lack of a prognathic jaw as the person I was responding to was suggesting.

Wow, really? I admit to having awful periods and i certainly know when THAT’S going on, but how do you tell when you’re ovulating?

Here’s some info about it.

I can just feel it, pop, right where my ovary is.

Having good sex is an evolutionary advantage for women, apparently. [I am the Goddess Kali and I endorse this message]
Breasts are a sensitive, erogenous zone. Maybe they just evolved size as a “pay attention to this part of the body, it likes to be stimulated” signal? It makes sense that women would enjoy being stimulated in that area anyway, as an incentive for them to keep breastfeeding their children. So why wouldn’t evolution take advantage of that to improve the hotness of human sex?

I don’t know one woman (who I know well enough to discuss our menses with) who doesn’t know when they’re ovulating and what’s going on. I’m sure some women have more subtle monthly changes, because we’re all different. I just don’t any women well who breeze through with no sign.

Wow, really? I admit to having awful periods and i certainly know when THAT’S going on, but how do you tell when you’re ovulating? I don’t know anyone who notices it that easily, i don’t think. women i’ve known who were trying to get pregnant went through lots of trouble to figure out when they’re ovulating.
