Lmp: apr18-19, almost 1wk having sore breasts, mild cramps(mostly leftside) and lower backpain.negative hpt 2 consecutive weekends.can be pregnant?

Pregnant?: See your friendly pharmacist and purchase an inexpensive urine test strip kit. If negative, test again in 7-14 days. Good luck.

Not if negative : Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection.
