Girls, good day everyone! Could anyone tell me if they know or have experienced something similar? The last period was on the 20th. There were never any delays, it always happened on time. On the 10th, I started spotting and it lasted for three days, and on the 14th, I started feeling nauseous but not too much. At the moment, it's been going on for nine days. Is it possible that I could be pregnant or is it just a hormonal imbalance? I haven't taken a test yet.
