### input:
I am trying for a baby and have had lots of symptoms this month which I have not experienced before. A week after ovulation I had cramps , my gum bled for 2 days when brushing and then it just stopped. I began gagging at nothing in particular and had headaches . I felt hideously tired and had to sleep there and then - luckily I was at home and my stomach had a weird fizzy feeling like I was excited or nervous for a good three days. At the weekend (2 days after ovulation) I needed to pee frequently and straight away and the gaging heightened. The day my period was due came and went, on the next day i did a test - negative. Two hours later my period appeared with cramps. usually i get cramps first then blood . I feel so confused! Could i still be pregnant. My period is mostly normal - although I have seen dark brown disharge at times and sometimes when i wipe the blood is red but very watery - resembling water colours. If I am pregnant, when could I test again? I have read that sometimes your ChatDoctor levels can be too low and the mentruation hormone can over power it. Is this true?

Hello thank you for your query. The symptoms that you describe might be related to periods, but are not confirmatory. Urine pregnancy tests are 97 % reliable - so if your test is negative, then you are most probably not pregnant. In the rare event of an early pregnancy not being detected, you can test again by a pregnancy kit test after a week, but better still is to consult a Gynecologist to have a definitive opinion. She would examine you and check for a pregnancy, at the same time assessing the weird symptoms you have. Pregnancy is best confirmed with a blood test / ultrasound compared to a urine test. Take care.
