I have a complicated question. I posted this in another forum on here but realized I probably should have posted it here instead. I am currently trying to conceive my second child and had a very hard time conceiving my first a few years ago due to a problem with my hormones. I last menstrated from June 11- June 17, 2015. I was 11 days late for my next period when I began bleeding. It was very sudden, very heavy, and lasted about 2 days before I spotted for 2 days and then nothing. My normal ones last 5-7 days, 4 of which are usually heavy so this was not normal for me at all. I took pregnancy tests on 7/15, 7/17, 7/19, and 7/21, all of them were negative, then began bleeding on the 21st. I assumed as of the day I started bleeding that I am not pregnant but my cervix is still high and closed, I am having random bouts of nausea, and my breasts and lower abdomen are tender. Could the bleeding that I experienced have been implantation and if it is a possibility, when should I take a test to find out? Due to low progesterone and a history of miscarriages (8 out of 9 pregnancies) I need to see a Dr immediately after I get a positive test but I do not want to go without a positive because it means time off of work and doctors bills that I don't need if I'm not pregnant. I know this is a long complicated question but please answer to the best of your ability. Thank you!
