i have been trying to get pregnant for a few months now, but i haven't had any success.. but just recently my partner came in me, on my ovulation day and now I'm a week late for my period but the only pregnancy symptoms I've been having are being tired all the time, frequent urination & lower back pain... I've taken 4 hpt's and they've all come back negative.. could i still be pregnant?
Yes, there is a chance.
Home pregnancy tests are unreliable. They are usually only accurate when saying you are pregnant. False negatives are very common. False positives are very rare.
Are you using your first morning urine, your wakeup pee? It makes a difference. Also, use a name brand test.
Give it another few days then see your doctor.
Your symptoms are not specific to pregnancy.
It can take up to a year for some couple to conceive and that's normal.
