3 weeks late..

Jes

Hey ladies, so I’m 3 weeks late.. I had a positive test the day I was supposed to get my period but ever since then I’m just getting faints.. or nothing.wondering if anyone has had any similar experiences? I had pink spotting on the 30th but that was it. Should I consider that a weird period and start a new month? Agh so confused.. anyone had faint lines and had a + blood test and still had a successful pregnancy?
