Symptoms the mother experiences with 12 weeks pregnant twins

Nausea and vomiting

Nausea and vomiting, sometimes referred to as morning sickness, are two of the most frequent symptoms that occur in the early stages of pregnancy.

At this point in the pregnancy, you may still experience those sudden and overwhelming impulses to vomit for no apparent reason. The fact that this is a twin pregnancy might even intensify your nausea.

Headaches

During pregnancy, a woman goes through a whirlpool of hormonal changes. This often leads to getting annoying headaches for the mother. The headaches during this week of the pregnancy might become more intense due to additional factors such as dehydration, stress, lack of sleep, etc. If your headache seems too extreme to handle, it is a good idea to talk to your OBGYN about this issue.

Frequent Peeing

This is where the extra weight of the babies comes to play. In your 12 weeks pregnant belly, twins take up double the space a singleton baby would take. The added weight and expanded uterus put extra pressure on your uterus, causing you to urinate more frequently. Moreover, the increased blood flow in your system as a result of pregnancy hormones also plays a role in frequent peeing.

Backache

In most cases, backaches manifest themselves during the later stages of pregnancy. However, given that having twins means carrying twice as much weight, a mother carrying twins may experience backaches earlier in her pregnancy.

Weight Gain

One of the signs that you are pregnant is that you will likely put on some extra weight. If you want to make sure that your babies are developing normally, it is crucial that you make sure that you are acquiring a healthy amount of weight during your pregnancy. Generally speaking, a mother who gives birth to twins will put on more weight than a mother who gives birth to a single baby.

Increased Discharge

Due to the increased amount of estrogen during this period of pregnancy, it is normal to have increased clear vaginal discharge. It helps protect your vagina from infection. However, if the discharge is green, yellow, or brown in color it is better to talk to your doctor about it; as it might indicate an infection.

Other than these, some additional 12 weeks pregnant with twins symptoms include dizziness, constipation, spotting, cravings for particular foods or an aversion to certain foods, and so on.
