Don't say we didn't warn you—getting it on will feel very different now.

You already know that getting it on feels way different now (and could require you to try positions you've never thought about)—but there may be other changes in store between the sheets, too.

1. Watch Out For Waterworks.
As your breasts prepare for nursing, they might jump the gun during sex. "Many women leak a bit of colostrum, a pre-milk fluid, from their breasts when that area is stimulated," says Lauren Streicher, M.D., associate clinical professor of obstetrics and gynecology at Northwestern University in Chicago and author of Love Sex Again: A Gynecologist Finally Fixes the Issues That Are Sabotaging Your Sex Life. "That's normal, but it may catch you both off guard." Mention this to your partner in the earlier stages of pregnancy if you suspect he'll be thrown by unplanned leakage later on. (Think: "So I heard that some women...") And if you're feeling a bit shy, consider keeping your bra on while getting busy—any excuse for cute lingerie, right?

2. The Orgasms Are Otherworldly!
"Some women experience much stronger climaxes during pregnancy," Streicher says. "An orgasm involves a contraction of the pelvic floor, and while you're carrying a baby you may feel more pressure there." Jill Blakeway, an acupuncturist and herbalist at the YinOva Center in New York City and author of Sex Again: Recharging Your Libido, adds, "the increased blood flow to your uterus and genitals also helps intensify the feeling." As you near your due date, another new sensation may join the mix: "My baby would kick when I came—I figured he enjoyed it too and I thought of it as a win-win!" confesses Cat M. of Hamilton, Australia.

3. You Might Get Cramps.
"When a pregnant woman climaxes, it may be accompanied by a uterine contraction—an involuntary muscle contraction that's different from preterm labor," Streicher says. "As long as the resulting cramps don't continue for long and aren't exceedingly painful, you're totally fine." They may be uncomfortable, though. "I would get pretty intense period-like cramps for a little while after I orgasmed," says Torria P. Dover, N.H. If the pain is persistent, severe, getting worse each time or accompanied by bleeding, bring it up with your doctor. Otherwise just breathe deeply and know that it will be over soon.

4. You May See Some Spotting.
If you're still early on in your run-up to Baby, you may be alarmed to see what looks like the onset of your period immediately after intercourse. Sarah H. of Winchester, Tenn. recalls, "During my first trimester I would bleed a little after sex and it scared my fiancé and me to death. No one had warned us about that!" In most cases, there's no reason to stress. "Your cervical tissue becomes softer during pregnancy, making it a little more likely to bleed—the way your gums tend to bleed more easily when you brush your teeth now," Streicher says. "There could also be a benign polyp on your cervix, or you may have a vaginal infection that's causing the spotting. But in nearly all cases it's nothing serious, and intercourse will not cause a miscarriage." Still, it's best to check in with your doctor to be sure. If postcoital spotting is persistent or occurs for the first time in your second or third trimester, it could be an indication that your cervix is changing and you need to get it checked out.

5. Your Sex Drive Can Swing Wildly.
The way Hollywood portrays it, when you're expecting, your sex drive either plummets (see: every sitcom wife who utters "Not tonight, honey" while preg) or goes into overdrive (see: that mom-to-be in the movies who can't wait to hop into bed, hormones surging). In reality, neither of these extremes tells the whole story. "Often your libido ebbs and flows throughout pregnancy," Blakeway says. Streicher adds, "It changes depending on how far along you are—typically, you may not have much of a sex drive in the beginning, it picks up in the second trimester, and by the third trimester you're feeling more uncomfortable and that drives your libido down. Still, it can be different for everyone." How much you're craving sex can also vary with each subsequent birth. "During my first three pregnancies I had a heightened libido, but with my fourth it was much lower, and intercourse was uncomfortable," says Asheley M. of Annapolis, Md. Bottom line: Whatever's going on with your mojo right now is totally normal. And when you are in the mood? Lucky girl, you get to experience new sensations with the partner who made your peanut possible in the first place.
