Hello Dear. Weeks from last menstrual period     Normal hCG levels (mlU/ml) 3     5-50 4     5-426 5     18-7,340 6     1,080-56,500 7-8     7,650-229,000 9-12     25,700-288,000 13-16     13,300-254,000 17-24     4,060-165,400 25-40     3,640-117,000 The above table (by American Pregnancy Association) says that your B hcg levels are normal. Regarding your brown discharge let me make you some facts clear. A thin, clear or white vaginal discharge (known in the obstetrics business as leukorrhea) is a normal part of having female parts. Healthy discharge comes in a variety of colors, though changes are usually signs something’s going on inside. And when you’re expecting, all those pregnancy hormones make your discharge heavier and thicker. But one of the biggest worries for pregnant women is brown discharge, probably because the color is so close to blood. The good news is, in the vast majority of cases some brown discharge is a totally normal part of being a woman. Brown discharge: As many women guess (and possibly fear, if they’re pregnant) brown discharge is discharge tinged with old blood. For whatever reason, some blood in your uterus took longer to come out — and as it gets older, it turns brown. That means you end up with either brown spotting or a brownish-colored discharge. What it means? If you’re pregnant, brown discharge more than likely does not mean something is wrong with you or your baby — in most cases, it’s completely harmless. The most common cause is irritation: As you know (or will soon find out), the surge of hormones and increased blood flow to the cervix can make it super-sensitive when you’re expecting. So sometimes, sexual intercourse or a pelvic exam can aggravate your cervix, resulting in a bit of brown discharge or even light spotting. If you’re nearing the end of your pregnancy, the brown stuff could also be a sign labor is near. A couple of weeks to a few days before you give birth, you’ll lose your mucous plug — a glob of mucous that seals off the opening of the cervix during pregnancy (you may not even notice it happen). Then in the days just before labor, you’ll likely see “bloody show,” or discharge tinged pink or brown with blood, which means your baby’s arrival is imminent. If you suspect you’re experiencing bloody show, call your health care provider immediately. But right now you need not worry for it. Hope i have answered your question.
