I have an 11 month old daughter whom I breastfeed. My period came back when my daughter was around 8 weeks old, but due to breastfeeding my cycle has been irregular. I didnt have a period for March and I had unprotected intercourse at the end of that month and the first week of April. I got what I thought was my period in April and May, but nothing for June yet. I took 4 hpt's in April, May and June and they all came back negative, however I have been experiencing pregnancy symptoms like frequent urination (in April), fatigue (in April), lower back pain (June), occasional cramping (May/June), morning dizziness (June), and I am feeling what I think is actual fetal movement. What are the chances I could be pregnant?
