Hi all! My last period was Sept. 25. Off and on in October I've had pregnancy symptoms like nausea overly tired wanting to eat more backaches. I've never been regular in my periods but I've only skipped a period when I found out I was pregnant with my other children. I did the essure in May 2011 and I wash regular until June of this year. June I started in the beginning of the month. July was middle of the month August I had 2 periods september was the end of the month and only a few days but very light which isn't like me and October no period. I am now 2 weeks late and both my home pregnancy tests came back negative. I went to the doctors saying I am sure I am pregnant but their urine and blood test came back negative also. Could I still be pregnant? My husband and I have 3 girls already and we agreed after our 3rd that we were done. Any help would be great.
