Crazy month with af

Sandra • mommy to a beautiful baby girl and baby boy
This month has been crazy. AF should her ugly head September 10th 11th 12th 13th but wasn't like normal 10th and 11th were lighter than normal for me stopped on and off talk to the 13th was very light on and off. Yesterday I was supposed to ovulate but started bleeding again on and off brown and red very light not enough to fill a tampon or pad today I've been feeling nauseous I took a pregnancy test yesterday but it came back negative. This month has been very confusing I have a big surgery coming up this month I'm just trying to find out if I am or not.. I was TTC until the 15th when I found out I need a big surgery.
