when you’re 12 weeks pregnant ,the symptoms such as morning sickness and fatigue will begin to subside as your hormones calm down.

But the downside is that they may be replaced with other symptoms such as dizziness and headaches, and more including:

Spotting at week 12

Bleeding or spotting in your 12th week of pregnancy may ring an alarm, but there could be several normal reasons for it starting with the fact that your cervix is a lot more sensitive, so simply having sex could trigger it.

However, what you should do is keep your OB informed especially if the flow is heavy.

This is normal and the good thing is that it greatly lowers the risk of vaginal infection.

But if the color of the discharge is not clear, but rather pink, brown or green, it could be signs of an infection so call your doctor right away.

Headache at week 12

You may experience headaches as early as 5 weeks pregnant, which in most cases they will start to intensify right around 12 weeks pregnant.

Headaches during pregnancy are mostly caused by a shift in hormone levels, dehydration, low blood sugar levels, stress or lack of sleep.

The best way to deal with it is to pay close attention to whats causing the headaches, but if it gets out of hand such as migraines, get in touch with your OB.
