Thought I would chime in. I have been with my husband for 12 years (married for 5 lived together for 7). We started TTC last June after our 4 year anniversary and silly me.. I thought it would be easy.... I had not been on birth control for something like 5.5 or 6 years so I figured I was regular... I never did the charting or temping as I get confused by it and it felt too science -y, but we stopped being careful and were I guess a mix of TTC and NTNP meaning there were several months we did not time the sex correctly. The thing is the longer you have been with your SO the less frequently you have sex and this is before adding the stress of TTC. Two months before I got pregnant, I went onto amazon.com and order a fertility blend tea and some ovulation tests. I took them the first month and drank the tea until I got my positive OPK, then stopped. The second month, I had a back injury and had to be on muscle relaxants for the first half of my cycle. I did the tea again, and then switched up the sex. I had sex 4 days before I would have ovulated, my predicted ovulation date, and two days later. The last time we DTD I started spotting and spotted on and off for the whole week, then I went to a workout class and noticed I looked insanely huge and my boobs were not as happy as they usually were with the work out, so I decided if I went the whole following day without any spotting or bleeding, I would take a test a day or two later as I normally spot some before my period and was not sure if I would start or not... I tested and it came back positive... Now I am 20 weeks pregnant and let me tell you, I have no idea what did it, but I do know that when you least expect it is when babies are conceived. Don't listen to anyone who says relax and it will happen because that doesn't change or help what is happening and you know your body, but I will say give it time. Unless you have been doing all this for at least a year, your time could be just around the corner... you never know...
