Hi im 27 i have two children i weigh 130 and im 5'6. I had a cervical biopsy the 22nd of august and spotted/bled til the 27th. My actual period was august 10th and usually runs between 28-35days in between periods lasting 2-3 days. hormone tests are normal. i had unprotected sex many times from august 26th til september 9th and took a pregnancy test this morning it was negative. Could i still be pregnant or is this most likely a result because of the biopsy. also ive had symptoms of allergies but also very tired and nauseas.
