Can you become pregnant if you are exclusively breastfeeding?

I have been breastfeeding since my son was born...he is 4 months old now. We only breastfeed. I haven't had my period which I know is normal, but have been feeling kind of more fatigued than usual and nauseous here and there.
How often does this happen?

yes you can get pregnant again while still nursing. I got pregnant while still nursing my daughter.
The first few weeks of nursing drained me, but by 4 months your tiredness might be pregnancy related. id get a hpt just to be sure since you cant even rely on your period at the moment.

Of course you can. Breastfeeding isn't a 100% guaranteed birth control.

"Three major factors will help to determine whether or not breastfeeding can be a useful method of birth control for you. The first factor is your baby being less than six months old. Second, your menstrual period should not have returned. Finally, your baby should be exclusively feeding on breast milk, and not being supplemented by other foods or formula, and not taking a pacifier. If you meet all of these criteria, breastfeeding reduces your chances of getting pregnant to about 2%."

Hey Breastfeeding mummies,

You definitely CAN get pregnant whilst breastfeeding!
There is an age old myth that says otherwise!

You can get a birth control pill from your doctor that will not effect your milk.

I learnt everything i need to know from an ebook I bought it has come in handy whenever i have a question!

maybe you should take a pregnancy test. its also normal to get your period back right away.- i did with both my kids. your cycle may have started and you got pregnant so no period. and if you aren't pregnant start using birthcontrol. because it happens often enough. sorry but whoever told you breastfeeding was birth control was mistaken.

You most definitely can! My Dr told us that basically once your body figures out to have a baby it wants to do it all the time! They told us to get on birth control at the 6 week postpartum appointment and then wait till it has fully kicked in to even have sex again (without protection) unless we wanted another one really quick!

of course you can. A hormone that is realeased while you are nursing helps to stop ovulation but its not a guarentee. If you have not had a period yet though then i wouldnt worry to much.

Ask my sister. The one who was conceived when I was four months old, and my mom was exclusively breastfeeding me.

In short, absolutely, yes. Even when using contraception.

yes you can get pregnant while breastfeeding. breastfeeding is not birth control.

how does this happen you ask??? well looks like you had unprotected sex. thats usually how people get pregnant.

1.5% of the time in the first 6 months, it is good contraception but not perfect

yes you can get pregant.
