Sometimes it happens. Is your baby not gaining any weight or appears irritated during feeds? This could be caused by tension, and frequent skipping of meals among other factors. Try taking more fluids, resting, and eating properly to increase breastmilk production. Additionally, you can seek assistance from a professional in lactation matters. 

Missed periods could indicate various possibilities, including pregnancy. Spotting a week before your expected period could be an early sign of pregnancy, but it's also important to consider other factors that might be causing the delay. Take a pregnancy test for confirmation

The way you position your body can indeed affect how comfortable you are, yet it does not accurately reflect the baby's position in your womb. Babies move around and shift in the womb when they are looking for the most comfortable spots. At 23 weeks, they have enough space to assume various positions. If you have concerns about fetal positioning or notice something unusual, the best thing to do is to see a doctor. They have the know-how to come up with advice and they stand by you through all the tests. Just think, every pregnancy is different, and qualified health care is vital to the health of you and your baby.
