Please be the stress....

This holiday season wasn't the best I've had for many reasons. One being that I found out my husband cheated on me...with a man. I had to move back in with my parents, no job, no money or car. Just when things start to look up I noticed Aunt Flo has been missing a while. I haven't seen her since Nov. 28 and I'm starting to get worried. Then I thought back and remembered my husband and I were intimate during my fertile window. We had be ttc for almost 9 months with no luck now that we're heading to divorce there is the possibility of being pregnant. I thought it could be stress of the situation. I've seen very light drops of blood but nothing more than that. I'm honestly too scared to test. I just have no clue what I would do if I was pregnant. I really can't afford a baby now...Mostly a rant and I'm sorry I just thought someone could send someone encouraging words. Or has anyone been through anything similar
