I am fortunate to have had a relatively smooth first trimester of pregnancy. No morning sickness, rarely threw up, and went about my usual activities.
So I was alarmed to have experienced some symptoms that are quite normal in the first trimester during the second trimester: spotting. In the first instance, my OB-GYN diagnosed that I had some infection, and I was asked to take antibiotics. But after two weeks, I've had some spotting again and pelvic pain. This might be because of too much walking. So I am again taking medications and on bed rest.
While I have not seen my OB-GYN yet, I just hope my "baba munchkin" is doing fine.
