Hello guys ❤️. I’m new to this ,

So I have not had my period since November and still till this day. I spotted brownish / light red. For 3/4 days but very little I know it not my period. I’m usually irregular but. Never for that long. I took 2 test. The second one was 4 days after the first one then I took a third one a week later and. The doctor said negative but to come back within 2 weeks if my period has not come to re check. I been feeling. Cramps. I feel the urge to use the bathroom Frequently Could it be to early. To tell if I’m pregnant. 😩 Help lol
