Missed period ?? Help

So a few weeks ago about 2 weeks after my period I spotted once pinkish whitish discharge. Few days later felt randomly nauseous threw out the day. Was supposed to get period according to glow about a week ago. Passed week and half been having period like cramps like if I was on my period. Lower back pains. Took two tests both negative... I'm just sitting waiting for a late period and it's not coming... Also been having super bad constipation. Been having a clear and whitish cream discharge not that heavy. Been very very hungry. Kinda freaked out can I still be pregnant????? HELPP. Been about 44 days since beginning of last period.
