Please help!

Patient: Hi, okay i picked pregnancy because I was unsure what else to put it under.. I took a few pregnancy tests last month.. the negitive line was very dark, and all of the positive lines were very very faint and then disappeard a few hours later. Ever since then, I still have menstural cramps with a little back pain, I will bleed for about a day or two every two to three weeks, I bleed after intercourse sometimes heavy sometimes not so heavy, followed by cramps and I have no pregnancy symptoms ( I already have one child so I’m used to the symptoms) but I have also gained a little weight and my face is breaking out. I am in the process of getting health insurance but I was unsure if you had any idea of what this could be?? THANKS SO MUCH!!
