I have 3 kids my youngest is 4 months, and I exclusively breastfeed with all 3. I did not have this issue with my other 2 and had a regular period while breastfeeding them both. After having my youngest I had very light bleeding for about 3 weeks. After that stopped I started to have (my regular period like) bleeding every 2 weeks. From Nov. to Dec. I had a regular 30 day cycle. I ovulated around Dec. 25th (I know because I have ovulation pain). However I did not have any sex from Nov. until Jan. 1st. My period is now a little over a week late but I know that with breastfeeding periods can be irregular. The only pregnancy symptoms I'm having, if any, is lower back pain, hot flashes, and insomnia. Could I be pregnant?
