Please advice

Hi, I have 3mos old baby. Is it normal na kabahan ka na mabuntis ulit??. Withdrawal Kami ng partner ko, I know na nilabas nya lahat pero di talaga mawala Yung worries ko na mabuntis ulit. Withdrawal na Kami for almost 4years.. plano Kong magpa IUD pero di pako nag memens since nanganak Ako. Ayaw ko ding mag pills (malimutan ko ngang I take Ang vitamins everyday, pano nlng Kong pills) Di ko talaga mapigilan mag overthink 😔 #advicepls #1stimemom
