### input:
My boyfriend and I have been trying to get pregnant. I stoped the pills 2 years ago and been trying since then and nothing happened. We went to the Dr 2 months ago and he did the sperm test and the result said it was really low. My ovulation was last week and we had sex during my ovulation day on the13th. I am expecting my mestruation on the 27th I am very regular. On the 18th and 19th I bled a little but it was not like the mestruation, it was a light red, pinkish color and i didnt need to use any tampon or anything because the bleeding was just when i pee. I feel some crams in my belly just like if it was the mestruation but its not suposed to come until the 27th. I was wondering if it is the impantation bleeding. I took a pregnancy test but it came out negative. I dont if its too soon for the pregnancy test. I was thinking about taking a blood test but maybe i should wait for the mestruation. Can you help me to figure this out please?

Hi there, I have understood your concern. I will suggest you the best possible treatment options. You are on right track for getting pregnant.  As you might be aware that if you get pregnant on or around the day of ovulation, it takes 7 days for the pregnancy to get implanted in the uterus. Some women can get slight bright red bleeding on that day, which is referred to as implantation bleeding. I will suggest you to wait at least 15 to 20 days after your day of ovulation, or wait till 27th February, which is your expected date of the cycle. If you happen to cross your dates, then please get mornings first sample of urine tested for pregnancy. In case of doubt blood beta Chat Doctor test and USG will be of help. Doing it earlier can not be conclusive. Also, I will suggest you to start with Folic acid, vitamin B 12 and Omega-3 supplements at least 3 months before you plan to get pregnant. This helps to prevent many problems during pregnancy and delivery. I hope this answer helps you. Thanks.
