Brown jelly like discharge

Hi mommies! I'm seeking for advice. Since the 5th week of my pregnancy i'm having brown jelly discharge na po. Not a lot, and not everyday. Madalas makita ko un after I wipe with tissue. Nung first trans v ko, wala pang nakitang embryo only gestational at yolk sac. Then my OB asked me to go on bedrest for 2 weeks and take heragest twice a day. Then after 2 weeks I went back, nakita na namin ang heartbeat ni baby with 129bpm.The OB said the baby is healthy and maganda daw ang pwesto nya. Sinabi ko ulit kay OB ung about sa brown jelly like discharge i'm having and she does not seem very alarmed. Ang sabi nya lang saken as long as hindi red spotting, hindi marami or walang cramps.I was no longer on bedrest too. She asked me to continue heragest for 2 weeks again but now only once a day. Now that were on our 8th week, minsan may brown discharge nanaman. I'm confused. What should I do? I know that walang spotting ang normal. But my OB isn't alarmed at all.. Thank you in advance mga mommy!
