Question ab Cramping & Ovulation
Tue, 12-20-2011 - 6:56pm
I have a question about cramping and ovulation. Does the cramping happen because of the rise in estrogen or does the cramping occur from the actual release of the egg? I ask because I only use opks and don't temp....but yesterday I got a positive opk and then this morning I had brown spotting and awful cramps. Do you all think I was ovulating at that moment or does all that indicate ovulation is on the way?

Sorry you haven't gotten a reply. I've been watching your post because I'm curious about the answer, too. From what I've heard, OPKs show a hormone surge, and you ovulate shortly after you get a positive. And brown spotting would be old blood, so it wouldn't make since for it to be from the same day. Hopefully somebody answers you soon.

I'm going to start charting next month. From what I've heard, OPKs are hard little suckers to figure out.

I too have been watching your post because I get ovulation cramping that lasts about 12 hours. I did some googling and unfortunately found that it can happen before you ovulate and that it can happen when/after you ovulate.

I'm very predictable.... cd 12 at 10/11pm I start getting the cramps. They grow in intensity and around 11am on cd13 they disappear. I also have a 28 day cycle. So do I ovulate on cd12 or cd13? And why not cd14 if I'm on a 28 day cycle? So odd.

Here are two links I found:

Not sure when this was posted but Im a labor and delivery RN so I may be of a little help. If you have a regular 28 day cycle then typically you would o on day 14 if your luteal phase is 14 days long but It may vary from month to month when you o by a day or two...the luteal phase is almost always consistent however....My OB and several I work with have told me I most likely I O on day 17 (cycle length is 31-32 days) and said if you bd starting three times a week after menstration and every other day up to your o day (and on day 13, 14 and 15) just to cover your bases you should eventually get pregnant within one year for most. Good luck!
