So I missed my period in October and November. On Nov 30 I started spotting. I spotted for about a week. Just very light bleeding, only enough to show up when I went to the bathroom. Well about 7 days ago I started what seemed like a normal period. Now for the past 2 days Its been extremely heavy with lots of very large clots. I was scheduled for my annual Paps 2 weeks ago but rescheduled because of what I thought was a period. My new appointment is Tuesday so weather I'm still bleeding or not, I'm going. I have no idea why this is happening again. 2 yrs ago, this exact thing happened and it ended up turning into me bleeding for an entire year with no break. Back then the doc found nothing wrong with me. Did STD tests, Paps, ultrasounds , blood work and everything was normal. Doc told me that they believed the weight gain caused it (gained 60lb in 6 mo after moms death). They put me on birth control then for 3 months and in that time i lost 40lbs. My period has been normal since. I have gained about 20lbs of the weight back over the past 11 months. Can weight gain really cause something this crazy? Should I be asking the doc to run a specific test?
