I'm 38 years old and over weight. My question is bc my period was supposed to start on 11-28-16, by cycle is around 33 days. On 1-25-17 I had implantation bleeding just 2 times when I wiped. So my period was supposed to start on the 29th of January and it hasent. So on the 31 I took a test first response and it came back - .On February 4th which it today I took one and in came back - again. I've been pregnant before, I have 5 kids and I have all the sustoms. I'm just wondering if it was implantation bleeding on the 25th would I b taking the test to early?
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. In case of regular 33 days cycle you can expect ovulation around 19th day,  so if conception occurred around that day you can expect implantation bleeding from one week to 10 days after.  According to this if implantation bleeding occurred it might have occurred around ending of December or beginning of January. If your periods are irregular we can't rule out the possibility of implantation bleeding on 25th January as you mentioned.  But as both times urine pregnancy tests gave  negative results the possibility of pregnancy is appearing less. If you are still having symptoms,  better to get evaluated to rule out the possibility of pregnancy. For that you can go for either ultrasound which will help in ruling the out the possibility of pregnancy and also in finding the other possible causes for delay in periods,  or you can go for blood test for pregnancy that is estimation of Beta HCG levels.  If  the level is less than 5 Milli International units per ml the possibility of pregnancy is almost ruled out. Hope I have answered your query I will be happy to answer any further follow queries. Take care.
