I had a surgical abortion 4 weeks ago, and all my symptoms were gone within a week. Now, since about 2 weeks ago, they've come back. I have had sex (with my long term boyfriend) and the condoms have broken so many times. 4 days ago, I took a test and it was lightly but clearly positive. I've taken one everyday until now (4 days) and they're all the same. Not lighter but not darker. Any ideas?
