I am 27 years old, and I have 2 children, both were healthy pregnancies, with no problems. Last summer I was pregnant but ended up being a tubal pregnancy due to a cyst that had developed on my right ovary. In November the cyst was removed and unfortunately my right ovary had to be removed also. I was told by my Dr. that I would still be able to have other children, since I still had another ovary. I am currently trying to get pregnant with my boyfriend, and have been doing everything that I have read on the internet, from increasing my folic acid intake, to being on the bottom during intercourse. Both my boyfriend and I are healthy and have never had major illnesses. I have noticed over the past few months, that my period has been very different. In July I had 2 periods, with both times they lasted for 5 days. In August after 28 days I had a period, which lasted only 3 days, which has never happened, I let it go for another month, and now in September, 26 days after my last period, this one only lasted 2 1/2 days. I want to be pregnant, but every one tells me to be patient, and not to think about it, and it will happen. Well, I want this bad, and its hard NOT to think about it. Are there any tips that I can try that I haven't heard of already? Please help. Thank you

You definitely can still get pregnant with only having one ovary.
When an ovary is removed, the other remaining ovary usually compensates for the absent one.

It can take most healthy couples a least a year before becoming pregnant.

I have had irregular periods since I first started, and now I'm 25 and they still are out of whack.

My husband and I have been trying to get pregnant for some time now...

Here are some tips that may help...

It's good idea to start tracking your cycle, count how many days your cycle is and from there you can start to determine when you should ovulate and be most fertile. Here is a site they may further help you know when you should ovulate.
American Pregnancy Association : Getting Pregnant: Ovulation Calendar

You could also use ovulation predictor kits. With you having irregular periods, you may have to use them quite frequently (as I do) so I would suggest buying them on the internet at Early Pregnancy Tests and Ovulation Predictor Kits for Home Use. That is where I get mine, they come in all different combo packs with a few tests, to a lot, and in combo with pregnancy tests, they are MUCH cheaper, and work just the same as the ones in the store.

You could also start tracking your BBT (you can Google this to get all the info). But basically when you do in fact ovulate, you body releases progesterone which is a heat-emitting hormone. This hormone causes your normal "waking" temp to rise. By charting, you will know that you certainly ovulated (as ovulation predictor kits only PREDICT that you SHOULD ovulate, they can not tell you that you actually did).

I also highly recommed you getting the book, Taking Charge of Your Fertility by Toni Weschler. It is a great book! It tells you all kinds of tips of how to tell by your own body signs when you are most fertile, among other things. It is a great resource!

I would visit your doctor and let them know you are trying to get pregnant. Most will do some bloodowork to make sure all your hormones are at the right levels to achieve pregnancy. My doctor also started me on Prometrium to regulate my periods to help.

If after about a year you still haven't managed to get pregnant, your doctor should be ready to step in and help. But all your tracking/charting will be great tools for you doctor to look at. By charting my BBT and using ovulation kits, my husband and I discovered that I wasn't ovulating every month. So my OBGYN ran a test on my husband which came back fine, and next will be sending me for a test to make sure my fallopian tubes aren't blocked. If that test comes back fine (which she is expecting it will) she is starting me on Clomid, a hormone that makes you ovulate.

I know it is very frustrating when you want to get pregnant but can't, but honestly getting pregnant is a detailed science, a lot of factors have to be just right, so hopefully some of these tips will help you.

Good luck! :)
