Brown spots everyday/ Haven't done prenatal yet/ 16 weeks pregnant

Ask ko lang po kung ano itong brown discharge ko everyday? Nag simula po ito nung 13 weeks ako, at my 13 weeks and 1 day meron po ako napapansin na brown discharge saken ongoing until at my 13 weeks and 4 days this time dinugo po ako like naka isang pad po ako pero walang masaket saken bleed lang talaga. Hindi pako ina accept magpa check up kasi inuubo ako for 2 weeks kaya until now at my 16 weeks wala pa akong record sa prenatal. PS: late ko lang nalaman na buntis ako.#firstbaby #pleasehelp #f1sTymMom #pregnancy #firstbaby
