Zainab, IA it's just due to the UTI, which is pretty common. Now I remember that I had some bleeding also, around 10 weeks. It was also brownish discharge, but we had an ultrasound and the baby was well, alhumdulillah.
NHA: may Allah make things easy for you sister. Do as much dua as you can. i felt depressed in the months before I got pregnant and the duas and dhikr are what got me out of it. I have issues with anxiety too so I know how you feel. It's so frustrating.
Hope everyone else is well.
