I am 26 years old. My husband and I started trying to get pregnant right from October 2012. After my first sex, I kinda got a brown spotting 2 days after my ovulation. I have a regular 28 day cycle and it lasts only for 2.5 days. When I was nearing my period time , I had unprotected sex and immediately I got a long stretch of liquid egg white like discharge and the next day I got my period.Is this something like chemical pregnancy? The next cycle which I had was for 3 days this time and was unusually heavy. Post these two cycles I had bad pain in my left leg,hip and abdomen . I met the doctor and did ultrasound and everything was normal. The next following cycle was normal. The fourth and fifth cycle I had unusual pain in my left leg,hip and pelvis which started post my ovulation and went off after I got my period. Now gradually all these pain went away and I feel normal for 6 and 7 cycle . Does all pain indicated chemical pregnancy? I am worried since some kinda pregnancy symptoms that existed in the first 5 cycles had gone and my hopes of getting pregnant is demotivated. Do you see something unusual? I never had painful cycles and now also it is gone. My ultrasound is perfectly fine. I am worried please suggest.
