My boyfriend left in march on the 15 the last time we had sex was on march 13 my period comes on around the 15 of every month. I had my period in April and May but not in June and in May it only stayed on for two days. MY Breast are sore and I am having lower back pains. But 8 years ago after my fourth child I had my tubes tied cut and burnt. Could I be pregnant?

I had light periods first 2 months. Do a home pregnancy test just to make sure
