Waalaikumassalam, sayang, kesian you've been through this, especially after 2 tahun TTC then finally dapat 2 lines. Chemical pregnancy ni memang sedih tapi the good news is it shows your body can conceive, so ada harapan! It doesn't automatically mean ada masalah with you or your husband; sometimes it's just a timing or chromosomal thing yang tak boleh elak. A few of my mum friends dapat chemical juga then eventually pregnant after, so jangan putus asa. Tapi sebab you've been trying 2 years, best you see a specialist together with your husband to do proper investigations, maybe hormones, sperm analysis, or other things, so boleh pinpoint if ada anything that needs attention. Supplements tu OK je tapi kan, sometimes we need more than that.
