Am I protected after Depo shot and unprotected sex?

The 17th starting and the 20th ending period is a pretty normal cycle. Having unprotected sex on the 22nd might expose you to the risk of getting pregnant. So, watch for possible symptoms like nausea, fatigue, and breast tenderness. If you're concerned, think about using emergency contraception or taking a pregnancy test. 

Toward the middle of the pregnancy, a smaller belly at 17 weeks might trouble you. If a belly is small, it can be because of the baby’s position, the way your body is holding the baby, or many other reasons. In the majority of cases, it's not a big deal when your health conditions are within normal limits. Continue to eat well and go to all of your pregnancy medical check-ins to ensure that you and your baby are healthy.

It's completely normal for periods to be late sometimes even if you have used protection. Common causes could be stress, a change in routine, or hormonal imbalance. If you are concerned, wait a few more days and then take a home pregnancy test. Remember that irregular periods can happen but it is always good to get checked out just in case. 

You might have a yeast infection. These are a type of infection that can be found in the vagina which begin to get itchy after a while and might emit white discharge. In some women, an imbalance of yeast can lead to an overgrowth where the vagina becomes too acidic. This is what happens when your vagina has too much yeast in it. You can purchase over-the-counter antifungal creams to help respond to yeast infections. 

You might face normal bre­astfeeding troubles. Fe­eling drained, achy arms and legs, nipple­s hurting - it happens when your baby bites while­ feeding. Babies bite­ during teething. Offer a te­ething toy first to soothe baby's gums. Try changing your breastfe­eding position to reduce nipple­ pain. Ensure proper latch to avoid discomfort.
