Oh, the world of pregnancy products. There are a million gizmos, gadgets, and apps galore that someone out there is going to say you absolutely need. But that鈥檚 not always the case; some of those so-called must-haves aren鈥檛 necessary 鈥 and some might actually be dangerous. Before you buy or register for everything your friends, mom-group, books, and blogs tell you to, check out which products you can nix from your list.

1. At-Home Fetal Monitor: That magic moment when you get to hear your baby鈥檚 heartbeat for the very first time is unlike anything you鈥檝e ever experienced. Sure, it sounds kind of like a muffled metronome that鈥檚 been filtered through Darth Vader鈥檚 mask, but it鈥檚 still beautiful. Now you don鈥檛 have to take a trip to the OB鈥檚 office to get a listen 鈥 you can buy your own at-home fetal monitor. Yay! Or not. Some experts believe that these monitors lull women into a false sense of security. A faulty monitor could also freak out the mama-to-be when nothing is really wrong.

2. Morning Sickness Bags: Yes, this is a real thing. You can actually buy disposable and 鈥渟tylish鈥 baggies that come complete with chic little designs on them. Seriously, save some money and reuse the free ones you get at the grocery store check-out.

3. Uterus Headphones: You want your baby to someday go to Harvard (preferably on a full scholarship), so you鈥檇 better get started early. Maybe you heard somewhere that playing classical music to your fetus will make her smarter later on (you know, after she鈥檚 actually born). Don鈥檛 believe the hype. While there鈥檚 nothing harmful about playing music to your soon-to-be baby, a special womb-y headphone set is totally unnecessary.

4. Vaginal Headphones: Yeah, you read that correctly 鈥 vaginal headphones. They stream music vaginally so that your baby can hear it better. You could invest in these鈥 or you could just sing to your baby. For free.

5. Groin Band: There are some legit reasons for buying a groin band during pregnancy. The compression product is meant to support inguinal and femoral hernias and help with prolapses, so if you have a real problem, go ahead and buy one. But if you鈥檙e just scared your nether region won鈥檛 stand up to pregnancy, skip it.

6. Social MediaMessenger: Oversharing is a major problem in our social media landscape. Apparently, we all need to be updated every time our 鈥渇riends鈥 do laundry, have a beer, eat a meal, or buy a coconut water. Well, the oversharing parade doesn鈥檛 stop at pregnancy. It just gets worse. Steer clear of products that, say, post to Twitter every time your baby kicks 鈥 you鈥檒l thank yourself later.

7. Perineal Oil: Perineal massage can really help you out when it comes to the great stretch of childbirth. But that doesn鈥檛 mean you need to use a pricey oil. A vitamin E oil or pure vegetable oil will work just as well as those super-fancy so-called pregnancy blends.
