30weeks pregnant

Worried about these past few weeks 😢. Dinugo ako saktong 28weeeks ko pero walang pain. Then nag pacheck up sa OB niresetahan ako. Onti onting nawawala until became brown discharge. After that may lumabas na buong dugo but its color black. Then check up again. And low lying placenta ako. Kaya bedrest muna. Then until wala na ng discharge mga ilang days yun. Tas kahapon may lumabas na naman na brown . Hayst i thought wala na talaga. So ayun . Its a sign ba na malapit na ko manganak? Wag naman sana , ayoko premature si baby 😢
