I'm 15 weeks pregnant and just got my NT scan and double marker tests done. I'm worried about my results and need to know if they're normal. My FBHCG is 193 ngmlis that okay? Also, my biochemical T21 risk is 1:178. Does that mean there's a significant risk? My nuchal translucency is 1.7 mm and NT MoM is 1.09. My report mentions the trisomy 21 risk is negative, as well as the trisomy 1318 screen. Can you help me understand what all this means?

Based on your report, your parameters appear normal: the free beta-hCG (193ngml) is within the typical range for 15 weeks gestation, the biochemical T21 risk (1:178) is considered low-risk, and the nuchal translucency (1.7mm) with a MoM of 1.09 is also within normal limits, and with the trisomy 21, 13, and 18 screens all reported as negative, your results indicate a low risk for these chromosomal abnormalities.

I've just started taking Primolut N 5 mg twice a day to delay my period, but it still began today. I'm not sure if I should keep taking the pills or stop. Is there any chance that my period might stop if I continue with them? And if I decide to quit, what happens with the two pills I've already taken? I'm really confused about what to do next.

Since your period has already started, its likely best to stop taking the Primolut-N. The tablets youve already taken may have a mild effect on the flow and duration, but they wont stop your period now. If you continue to have concerns or if you experience abnormal bleeding, its important to check with your doctor for personalized advice.

I recently had my third C-section and got a tubectomy. Now Im considering reversing the tubal ligation because I want to have another baby. I'm concerned about what risks might come with a fourth C-section. Could you help me understand if this is safe?

Can someone actually get pregnant if there's no penetration involved but just rubbing a naked penis around the vulva? I've heard that precum could be a factor, so how real is the risk here? I'm kinda worried and curious about how this works.

Yes, it is possible to get pregnant from genital rubbing if precum (pre-ejaculatory fluid) comes into contact with the vaginal area. While the chances are lower compared to direct penetration, sperm in the precum can still lead to pregnancy.
